4d5b401f00 try to fix some performance problems with the internal index management:
- ensuring that ordered indexes stay ordered during remove
- no unnecessary ordering checks
- better test logic in crawl stacker

c6880ce28b removed the permanent cache flush and replaced it with a periodic cache flush
The cache is now flushed only for one second every ten seconds. During a crawl the cache
fills up completely, and is only flushed if space is needed for more documents.

b6bba18c37 replaced the storing procedure for the index ram cache with a method that generates BLOBHeap-compatible dumps
this is a migration step to support a new method to store the web index, which will also based on the same data structure. made also a lot of refactoring for a better structuring of the BLOBHeap class.

7535fd7447 - refactoring of CrawlEntry and CrawlStacker
- introduced blocking queues in CrawlStacker to make it ready for concurrency
- added a second busy thread for the CrawlStacker
The CrawlStacker is multithreaded. It shall be transformed into a BlockingThread in another step.
The concurrency of the stacker will hopefully solve some problems with cases where DNS blocks.

1779c3c507 - added a read cache to the RAFile interface to RandomAccessFile
- added a write buffer to BLOBHeap
- modified the BLOBBuffer (is now only to buffer non-compressed content)
- added content compression to the HTCache
The new read cache will decrease the start/initialization time of BLOB files,
like the HTCache, RobotsTxt and other BLOBHeap structures.

0edec2b760 FULL redesign of algorithms in htmlTools to encode/decode strings from/to unicode and html.
The old process used a not really efficient way to detect html encoding strings in texts.
All calling methods had been adoped to call the new class in an enhanced way with less parameters.

Many classes in interfaces used a XML encoding only (instead of full html conversion from unicode to html); this behavior was not changed with this commit but should be controlled again since it points out possible XSS leaks

826ca79735 refactoring and new architecture to store the files of the web cache:
- files are not stored any more as individual files
- a new database structure using BLOBHeap files stores many cache entries in common files
- all file-writing procedures had been migrated to generate byte[] objects which are written with the new database methods

this is only an intermediate step to the final architecture, where cached files are written together with their metadata in one single database structure.

3fbfd5a78b * fix for non-changing offset on new search term
* dht-heap doesn't has to be deleted (5097), we simply write a new one on exit
* do not install YaCy in startup because a Windows-shutdown might corrupt something. Installing YaCy as a service would solve this.
