method. This is much faster and produces less blocking when using the
Compressor class which is used by the HTCache. I.e. picture search is
much faster now.
better-ranked search results. without that pauses the result page will
only contain links from the peer that answers first which is not a good
average picture of all the peers that provided results
- 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.

- many speed/performance hacks
- added solr charding and new charding web interface
- added option to switch off the yacy index when using solr
- added new fail-url categories which are used to make a distinction which fail-urls to be sent to solr
- refactoring/renaming of some method names to distinguish host/url hashes better
- a large number of bug/npe fixes

This time it works like this:
- each peer provides its ranking information using the yacy/idx.json servlet
- peers with more than 1 GB ram will load this information from all other peers, combine that into one ranking table and store it locally. This happens during the start-up of the peer concurrently. The new generated file with the ranking information is at DATA/INDEX/<network>/QUEUES/hostIndex.blob
- this index is then computed to generate a new fresh ranking table. Peers which can calculate their own ranking table will do that every start-up to get latest feature updates until the feature is stable
- I computed new ranking tables as part of the distribition and commit it here also
- the YBR feature must be enabled manually by setting the YBR value in the ranking servlet to level 15. A default configuration for that is also in the commit but it does not affect your current installation only fresh peers
- a recursive block rank refinement is implemented but disabled at this point. it needs more testing
Please play around with the ranking settings and see if this helped to make search results better.

- added more properties to solr index
- refactoring
- more constants in switchboard
- fix for some NPEs
- recognition of more images
- removed synchronization in HandleMap (obviously not necessary?)
- added a nolocal configuration to remove excessive dns lookup (works only on allip - default off). Indexes produced with this setting are all flagged with 'local' and are (on purpose) not usable for freeworld because they will be rejected as beeing local.

- new concurrent score map using atom operation from java concurrency classes
- redesigned difference beween StaticScore and Dynamic Score into ScoreMap and ReversibleScoreMap allowed that many classes can now use simple ScoreMap Objects which can be used better in concurrent environments using the ConcurrentScoreMap
- switched from DynamicScore to ConcurrentScoreMap usage wherever possible
