and replaced old fist hash computation by new method that tries to find a gap in the current dht
to do this, it is necessary that the network bootstraping is done before the own hash is computed
this made further redesigns in peer initialization order necessary

- removed web structure picture from indexing menu and grouped it together with htcache monitor
- added a database for terminated crawls, when a crawl is finished it is automatically moved to the new database
- extended crawl profile edit servlet, shows now also terminated crawls
- option that was used to delete profiles is now redesigned to a function that moves the current crawl to the terminated crawls and removes all urls from the current queues!
- fixed here and there problems with indexing queues
- enhances indexing speed by changing cache flush sizes.
- changed behaviour of crawl result servlet: the list of crawled urls is shown if there is one, othevise the overview window is shown
attention: the new profile databases are not compatible with the old one. current crawls will be lost! the web index is not touched.
next steps: the database of terminated crawls can be used to start with them a new crawl. This is useful if one wants to re-crawl specific pages and wants to use a old crawl profile.

1. avoid adding duplicate file name entries in config properties for lists,
2. correctly merge all path masks from all list files for the same host masks,
3. rewrite helper methods standard java methods for Collection transformations,
4. merged various methods with identical functionality for different Collection implementations into one,
5. minor refactoring to improve code readability.

search profiling showed, that a major amount of time is wasted by computing url hashes. The computation does an intranet-check, which needs a DNS lookup. This caused that each urlhash computation needed 100-200 milliseconds, which caused remote searches to delay at least 1 second more that necessary. The solution to this problem is to attach a URL hash to the URL data structure, because that means that the url hash value can be filled after retrieval of the URL from the database. The redesign of the url/urlhash management caused a major redesign of many parts of the software. Since some parts had been decided to be given up they had been removed during this change to avoid unnecessary maintenance of unused code.

it is necessary for the new search process that will do automatic re-searches
a positive effect is, that when a re-search is done it can be monitored how many
results had been contributed from other peers. The message for this contribution
was moved from the end of the result page to the top.
* enhanced re-search time when a global search was done an the local index has
already a great number of results for this word
* re-organised presearch computation; must be further enhanced

after downloading a release using the download button on the status page
the user can choose any of the downloaded versions for a update.
this enables also a downgrade to a older version.
when the update button is pushed, yacy terminates, installes the choosen version

we will provide two different releases in the future, one standard release and one 'pro'-release.
the 'pro'-release contains all additional parsers AND has different default performance values.
The pro-version differs therefore from the previous 'all'-version by this default values.
The pro-configuration is automatically choosen if the libx-folder exists. If a version is once initialized, its configuration stays independently from an existing libx folder.
The ant targets had been changed. There are now 3 different targets to create standard and pro-releases, and one target to upgrade:
- dist: creates a standard release (only, no libx target any more)
- distPro: creates a pro-release (includes the libx)
- distExt: creates a libx-release which includes the libx-folder only. It may be used to upgrade from standard to pro
Furthermore, the naming of 'dev'-releases had been removed.

- all web page parsing operations will now increase a web structure file
- the file is computed in memory and dumped at shutdown-time to PLASMASB/webStructure.map in readable form (not a database)
- the file can be used externally to analyse the link structure of the crawled pages
- the web structure can also be retrieved using a xml-interface at http://localhost:8080/xml/webstructure.xml
- the short-term purpose is the computation of a link-graph image (before linuxtag!)
- a long-term purpose could be a decentralized computation of the citation rank

- the network configuration page shows a new option: robinson clusters
- when a global search is made, all robinson peers are excluded, but:
- robinson peers/clusters that provide peer tags and where search words match
such tags, they are included in global search. Therefore, robinson peers/clusters
support the global yacy network with their indexes, without doin DHT-exchange

* new layout for image-search results: replaced the old one with spans and tables inside (not valid) with new divs, now each image snippet container has the same size
TODO:
* the ids of the snippetLoading-divs aren't valid because ids must start with an alphabetic letter or an underscore, they have to be prefixed
* in the returned snippet-xml is an unresolved pattern for status (the status is only set for text snippets)

this shall be used to store a fragment of the index on another physical device,
to split IO load and enhance access speed. The index is splitted in such a way
that the LURLs are stored to the secondary location, and the RWIs to the primary
location. This is especially useful for environments where symbolic links are
not possible and may cause IO access even if there is no write access to the
device which hosts the symbolic link.

- the general NURL-index for all crawl stack types was splitted into separate indexes for these stacks
- the new NURL-index is managed by the crawl balancer
- the crawl balancer does not need an internal index any more, it is replaced by the NURL-index
- the NURL.Entry was generalized and is now a new class plasmaCrawlEntry
- the new class plasmaCrawlEntry replaces also the preNURL.Entry class, and will also replace the switchboardEntry class in the future
- the new class plasmaCrawlEntry is more accurate for date entries (holds milliseconds) and can contain larger 'name' entries (anchor tag names)
- the EURL object was replaced by a new ZURL object, which is a container for the plasmaCrawlEntry and some tracking information
- the EURL index is now filled with ZURL objects
- a new index delegatedURL holds ZURL objects about plasmaCrawlEntry obects to track which url is handed over to other peers
- redesigned handling of plasmaCrawlEntry - handover, because there is no need any more to convert one entry object into another
- found and fixed numerous bugs in the context of crawl state handling
- fixed a serious bug in kelondroCache which caused that entries could not be removed
- fixed some bugs in online interface and adopted monitor output to new entry objects
- adopted yacy protocol to handle new delegatedURL entries
all old crawl queues will disappear after this update!

- permanent cache flush is switched off. The optimized cache flush
works better if it is a large number of collections that is flushed
together
- the flush size can be configured instead the flush divisor. There is
only one size for all flushes
- collection records that shall be removed during collection transition
(jump from one collection file to another) are now not really removed
but only marked in RAM. add-operations to the collection use these
marked collection spaces

Such constraints may formulate specific restrictions to web searches
This is implemented by scraping information for constraints from a web
page during parsing, and storing flags to the pages within the web index.
In this first step, only information for index pages ("index of", directory listings)
are scraped and stored in flags
- added new flag class kelondroBitfield
- added scraper method in condenser
- added bitfield structure for all scrape types (see also condenser)
- added bitfield structure for appearance locations (see RWIEntry)
- added handover protocol for remote search and index distribution

- the oldest entries can easily be identified, used for re-crawl und
deleted
- The complete database can be limited to a specific size (as wanted many times)
