- added a memory limitation in the zip parser and the pdf parser
- added a search throttling: if there are too many search queries are still to be computed, then new requests are not accepted for some time. if after a one second still no space is there to perform another search, the search terminates with no results. this case should only happen in case of DoS-like situations and in case of strong load on a peer like if it is integrated in metager.
- added a search cache deletion process that removes search requests in case that throttling happens

used a ASCII String <-> byte[] conversion wherever possible. Many Strings in YaCy are hashes which are pure ASCII (base64 hashes).
The new ASCII String <-> byte[] conversion method have less computation overhead than the UTF8 conversion.

- added option to crawler to send error-URLs to solr
- changed solr scheme slightly (no multi-value fields where no multi values are)

(directly or indirectly) and it grants a crawl-delay of 0. Then all forced pause mechanisms in YaCy are switched off and the domain is crawled at full speed.
crawl delay values can be assigned to either
- all yacy peers using the user-agent yacybot
- a specific peer with peer name <peer-name>.yacy or
- a specific peer with peer hash <peer-hash>.yacyh

- the own seed file gets the lead for storage of the peer name
- exchanged default peer name generation method with one that does not use the local ip
- default peer names are now strings starting with '_anon'
- added another switch to suppress forwarding to ConfigBasic if the name was already changed
- replaced all usages of the yacy.conf peerName with access to the local seed
- changes to the peer name are now applied directly and not after the next peer ping

- this recording is then used to redirect from the Status.html page to BasicConfig in case that servlet was never submitted
- this acts as an addition to the new default pop-up page 'index.html' which offers an administration link to Status.html. For a first-time user this then redirects directly to the former start page BasicConfig.html

(after this patch, is the rule from above really nesseccary,
the crawler also checks the robots.txt)

- added a new queue 'noload' which can be filled with urls where it is already known that the content cannot be loaded. This may be because there is no parser available or the file is too big
- the noload queue is emptied with the parser process which indexes the file names only
- the 'start from file' functionality now also reads from ftp crawler

- added a generic skin which is filled with actual color assignment using a servlet
- enabled css servlets
- added a generic color scheme in configuration file
- added configuration input in Customization/Appearance servlet
- added a jquery color picker widget
- placed color picked widget to input field of generic colour definition input fields

- migrated the 'yacy' user agent to 'yacybot' in many client methods since the 'yacy' user agent is only used for the proxy

- remove the library
- added two classes from the httpclient-3.1 library as source code to YaCy because these classes were used by the YaCy HTTP Server
- modified the added classes ChunkedInputStream and ContentLengthInputStream in such a way that:
* there are no more dependencies to httpclient-3.1
* these classes had been simplified to serve only the purpose for the YaCy httpd

the home path can now be distinguished between
- data home; the path where the DATA directory is created
- application home; everything else
This will make it possible to store application data on Mac releases within the
~/Library/YaCy
directory; a place where Mac applications write their data.
Similar techniques will be possible for debian and windows.
To use the new data path, YaCy can be started with
-start <data path>
or
-gui <data path>

moved http date methods from DateFormatter to HeaderFramework
changed logging to log4j

Here a new concept called 'search heuristics' is introduced. A heuristic is a kind of 'shortcut' to good results in IT, here for good search results. In this case it will be used to get a very transparent way to compare what YaCy is able to produce as search result and what g**gle produces as search result. Here is what your can do now:
- add the phrase 'heuristic:scroogle' to your search query, like 'oil spill heuristic:scroogle' and then a call to scroogle is made to get anonymous search results from g**gle.
- these results are _not_ taken as meta-search results, but are used to instantly feed a crawling and indexing process. This happens very fast, here 20 results from scroogle are taken and loaded all simultanously, parsed and indexed immediately and from the results of the parsed content the search result is feeded, along to the normal p2p search
- when new results from that heuristic (more to come) get part of the search results, then it is verified if such results are redundant to existing (they had been part of the normal YaCy search result anyway) or if they had been completely new to YaCy.
- in the search results the new search results from heuristics are marked with a 'H ++' and search results from heuristics that had been already found by YaCy are marked with a 'H ='. That means:
- you can now see YaCy and Scroogle search results in one result page but you also see that you would not have 'missed' the g**gle results when you would only have used YaCy.
- to make it short: YaCy now subsumes g**gle results. If you use only YaCy, you miss nothing.
to come: a configuration page that let you configure the usage of heuristics and get this feature by default.

The finalize method prevents that the memory, used by the objects containing the finalize method, is collected and available for the garbage collector. Instead, the memory allocated by such classes are enqueued to a java-internal finalize queue runner. This slows down all operations that uses a lot of object containing finalize methods.
this fix does not remove all finalize method, but such that may be used for throw-away objects that are allocated many times. This should cause a better run-time performance and less OutOfMemoryErrors

this was done because that servlet may be used for wget/cronjob
triggered crawl starts and it appears to be confusing that the
name of the crawl start servlet looks like a pure monitoring tool.
