- added special rule to balancer to omit forced delays if cache is used exclusively
- extended the htCache size by default to 32GB

- better control to the cache by using combined request-header and content access methods
- refactoring of many classes to comply to this new access method
- make shure that the cache is always written if something was loaded
- some redesign of the process how http response results are feeded into the new indexing queue
- introduction of a cache read policy:
* never use the cache
* use the cache if entry exist
* use the cache if the proxy freshness rule confirmes
* use only the cache and go never online
- added configuration options for the crawl profiles to use the new cache policies. There is not yet a input during crawl start to set the policy but this will be added in another step.
- set the default policies for the existing crawl profiles. If you want them to appear in your default profiles you must delete the crawl profiles database; othervise the policy is 'proxy freshness rule'
- enhanced some cache access methods in such a way that unnecessary retrievals are omitted (i.e. for size computation). That should reduce some IO but also a lot of CPU computation because sizes were computed after decompression of content after retrieval of the content from the disc.

- removed the plasma package. The name of that package came from a very early pre-version of YaCy, even before YaCy was named AnomicHTTPProxy. The Proxy project introduced search for cache contents using class files that had been developed during the plasma project. Information from 2002 about plasma can be found here:
http://web.archive.org/web/20020802110827/http://anomic.de/AnomicPlasma/index.html
We stil have one class that comes mostly unchanged from the plasma project, the Condenser class. But this is now part of the document package and all other classes in the plasma package can be assigned to other packages.
- cleaned up the http package: better structure of that class and clean isolation of server and client classes. The old HTCache becomes part of the client sub-package of http.
- because the plasmaSwitchboard is now part of the search package all servlets had to be touched to declare a different package source.

- The indexing queue was a historic data structure that was introduced at the very beginning at the project as a part of the switchboard organisation object structure. Without the indexing queue the switchboard queue becomes also superfluous. It has been removed as well.
- Removing the switchboard queue requires that all servlets are called without a opaque generic ('<?>'). That caused that all serlets had to be modified.
- Many servlets displayed the indexing queue or the size of that queue. In the past months the indexer was so fast that mostly the indexing queue appeared empty, so there was no use of it any more. Because the queue has been removed, the display in the servlets had also to be removed.
- The surrogate work task had been a part of the indexing queue control structure. Without the indexing queue the surrogates needed its own task management. That has been integrated here.
- Because the indexing queue had a special queue entry object and properties attached to this object, the propterties had to be moved to the queue entry object which is part of the new indexing queue withing the blocking queue, the Response Object. That object has now also the new properties of the removed indexing queue entry object.

* autoupdate completely disabled, display hint
* restart-button in interface works!
* moved all build-Variables to yacyBuildProperties
* fixed some warnings

- added migration of code of settings pages (hmm.. does not work correctly yet, sorry)
- more refactoring
- removed more unused code

high-performance search query situations as seen in yacy-metager integration showed deadlock situation caused by synchronization effects inside of sun.java code. It appears that the logger is not completely safe against deadlock situations in concurrent calls of the logger. One possible solution would be a outside-synchronization with 'synchronized' statements, but that would further apply blocking on all high-efficient methods that call the logger. It is much better to do a non-blocking hand-over of logging lines and work off log entries with a concurrent log writer. This also disconnects IO operations from logging, which can also cause IO operation when a log is written to a file. This commit not only moves the logger from kelondro to yacy.logging, it also inserts the concurrency methods to realize non-blocking logging.

- added &meanCount= to query string
- &meanCount=0 ==> no suggestion, no performance loss
- sorting suggestions by sb.indexSegment.termIndex().count()

- portalsearch: introduced yconf.load_js and yconf.load_css
- yacysearch.html still having problems with focus after sidebar is loaded
- yacysearchtrailer.json seems not to be valid json for ?nav=all

- added a synchronization in pdf parser which should help to avoid deadlocks that occur when displaying several search results pointing to pdf sources
- fixed smaller bugs in navigation

- by default the navigator computation if off for servlet yacysearch.html, but:
- the servlet is called by default with a option to switch navigator results on
this will prevent that metasearch users will get slow results that are caused by unnecessary computations

- added a analysis method that counts bytes that could be saved in case the new HandleMap can be applied in the most efficient way. Look for the log messages beginning with "HeapReader saturation": in most cases we could save about 30% RAM!
- removed the old FlexTable database structure. It was not used any more.
- removed memory statistics in PerformanceMemory about flex tables and node caches (node caches were used by Tree Tables, which are also not used any more)
- add a stub for a steering of navigation functions. That should help to switch off naviagtion computation in cases where it is not demanded by a client
