with this fix search results are (even) faster.
Also enhanced: image search. This is now speeded up using a image search result look-ahead

- the search request cache can now get as large as 1000 entries
- if more entries arrive, unused are deleted
- the elements may stay in the cache up to 10 minutes and longer if they are used
- the elements are deleted earlier that 10 minutes if the memory gets low
This commit was mainly done for metager-feeding peers that have a query load of 50000 queries each day. Also added:

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>

- the scheduler extends the option for re-crawl timing. Many people misunderstood the re-crawl timing feature because that was just a criteria for the url double-check and not a scheduler. Now the scheduler setting is combined with the re-crawl setting and people will have the choice between no re-crawl, re-crawl as was possible so far and a scheduled re-crawl. The 'classic' re-crawl time is set automatically when the scheduling function is selected
- removed the bookmark-based scheduler. This scheduler was not able to transport all attributes of a crawl start and did therefore not support special crawling starts i.e. for forums and wikis
- since the old scheduler was not aber to crawl special forums and wikis, the must-not-match filter was statically fixed to all bad pages for these special use cases. Since the new scheduler can handle these filters, it is possible to remove the default settings for the filters
- removed the busy thread that was used to trigger the bookmark-based scheduler
- removed the crontab for the bookmark-based scheduler

- every process that is monitored with the API Steering interface can now be scheduled!
- added input methods in Steering interface to set a scheduling time
- added a view on the steering api that shows only crawl jobs inside the Crawl Profile servlet
- added a scheduling call process in the cleanup process handler that triggers the scheduled processes
This causes that the cleanup now also looks for scheduled processes. Such processes are therefore not executed at
the same time as given in the target execution time but they will be executed within the cleanup process time window.

The gui currently does nothing else than providing a search window that sends the search string to the browser
The gui is started when YaCy is started with the option -g or --gui, like
./startYACY.sh -g
The gui will primary be used to provide a 'real' macintosh version that can be started and operated like any other macintosh application. A special mac application wrapper will follow.

some file types are containers for several files. These containers had been parsed in such a way that the set of resulting parsed content was merged into one single document before parsing. Using this parser infrastructure it is not possible to parse document containers that contain individual files. An example is a rss file where the rss messages can be treated as individual documents with their own url reference. Another example is a surrogate file which was treated with a special operation outside of the parser infrastructure.
This commit introduces a redesigned parser interface and a new abstract parser implementation. The new parser interface has now only one entry point and returns always a set of parsed documents. In case of single documents the parser method returns a set of one documents.
To be compliant with the new interface, the zip and tar parser had been also completely redesigned. All parsers are now much more simple and cleaner in its structure. The switchboard operations had been extended to operate with sets of parsed files, not single parsed files.
additionally, parsing of jar manifest files had been added.

lets try that. If we run into a memory problem because of too many 2-letter-words, then we must introduce whitelists for 2-letter words.

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.

implemented a hint from dulcedo "use site: - operator as crawl start point".
YaCy already was able to search using a site-constraint. This function is now extended with a instant crawling feature.
When you now use the site-operator, then the landing page of the site iand every page that is linked from this page are loaded, indexed and selected for the search result within that search request. When the remote server responds quickly enough, then this process can result in search results during the normal search result preparation .. just in some seconds.

a cache access shall not made directly to the cache any more, all loading attempts shall use the LoaderDispatcher.
To control the usage of the cache, a enum instance from CrawlProfile.CacheStrategy shall be used.
Some direct loading methods without the usage of a cache strategy have been removed. This affects also the verify-option
of the yacysearch servlet. If there is a 'verify=false' now after this commit this does not necessarily mean that no snippets
are generated. Instead, all snippets that can be retrieved using the cache only are presented. This still means that the search hit was not verified because the snippet was generated using the cache. If a cache-based generation of snippets is not possible, then the verify=false causes that the link is not rejected.

- removed concurrency overhead for small number of index normalizations as it happens during remote search
- removed 'load only parseable' constraint for snippet fetch because some resources may not have any url file extension and these had therefore not been parseable and searcheable since they may become parseable after loading when their mime type is known
- this partly fixes some problems with http://forum.yacy-websuche.de/viewtopic.php?p=20300#p20300 but more changes are necessary to get all expected search results
