- ensuring that ordered indexes stay ordered during remove
- no unnecessary ordering checks
- better test logic in crawl stacker

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.

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.

- 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.

- modified and activated write buffer
- increased cache flush factor
- fixed a problem with deadlocking of indexing process

- added javadoc for new concurrent intialization in kelondroBytesLongMap
- switched default value for commons storage to false
- version step

- applied knowledge about concurrent files stream reading and index processing from the wikimedia reader
to the EcoTable initialization process: the file reader is now concurrent to the index generation
- changed also some initialization processes to avoid some pauses during initialization

- added hash to HTCACHE storage files which will make it possible to join separate caches by just copying files

- two different computations (but mathematical equivalent) of the DHT distance had been consolidated
- moved from 0.0 .. 1.0 double-range position computation to 0 .. Long.Max range for DHT targets
- added fast Long - to - hash computation
- high-precision target computation of gaps for new peers
- added new target computation for horizontal and vertical DHT targets (not yet in use)
- old horizontal-only DHT targets will be upwards compatible to new horizontal and vertical DHT positions

with index.storeCommons=false all currently stored commons are deleted!
Default is now 'true', but in future full releases it will be switched to 'false'

- removed the now superfluous HT storage thread
- reduced number of file decompression by shifting the compression moment to the future

- entries are buffered and written as stream with many entries at once (saves many IO accesses)
- entries are compressed with gzip: increases capacity of cache
- concurrency for stream-writing and compression: all writings to the cache are non-blocking

- 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.
