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.

divided that class into three parts:
- the peers object is now hosted by the plasmaSwitchboard
- the crawler elements are now in a new class, crawler.CrawlerSwitchboard
- the index elements are core of the new segment data structure, which is a bundle of different indexes for the full text and (in the future) navigation indexes and the metadata store. The new class is now in kelondro.text.Segment
The refactoring is inspired by the roadmap to create index segments, the option to host different indexes on one peer.

- increased default memory size to 180MB
- fixed possible bug in http client reset (there was a deadlock)
- bug in BOBHeap marked, but not solved, cause is still unknown.

- added some debugging output to balancer to find a bug
- removed unused classes for index collection handling
- changed some default values for the process handling: more memory needed to prevent OOM

This is a preparation to introduce other index tables as used now only for reverse text indexes. Next application of the reverse index is a citation index.
Moved to version 0.74

this option was never used and there is also no use to set other columns but the first as the primary key. as a result, access methods to the key do not need to compute key positions, and they work faster.

- 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.

- removed the online status property. This influenced the proxy behavior and created some complexity that was not needed because the online status was never used as it was ceated for (offline browsing)
- checked all proxy identification procedures during crawling and enhanced transparency and error checking
- fixed a proxy identification routine that caused the wrong selection of the proxy result queue

- removed distinction between header file types for http and ftp; ftp is simulated by using http properties
- removed all old resourceInfo classes that handled this distinction
- introduced a new distinction between http request and http response objects
- unified new response objects with two other object types that had been introduced elsewhere
- changed all servlet call methods to use the new http request header object type
- divided static object keys for http header properties into request and response types
- refactoring here and there (a large number of type changes and many methods merged/moved)

- removed unnecessary code (unused variables, String.toString)
- corrected some calculations (cast int to double or long ;)
- improved little performance (using Integer.valueOf() instead of new Integer)
- log if some File-actions fail (mkdir(), delete(), ...) and some ignored exceptions
- finalized some (more) fields
- finally close some streams
- made inner classes static if not using environment
- generalized some equals (from specificClass to Object)
- fixed some potential nullpointer accesses

- moved constants from plasmaSwitchboard to own class (all 232 ;)
- moved remoteProxy-Methods to httpRemoteProxyConfig, better names
- removed some unnecessary code (else-statements)
* formatting (correct indentation)
* minor bugfixes (due to findbugs.sf.net)
* hopefully fixed "missing quote" (announcing StringParts as UTF-8)

- added option to set minimum crawl delta for domains in balancer
- added default values to crawl deltas in yacy.init
- added configuration for these deltas in performance queues
- enhanced performance setting computation (more time for indexing queue for a faster flush
- remote crawling is now enabled during local crawling if indexer has space and time for more links
- added database stub for new distributed file system
- refactoring of time computation to get an abstraction level that will be used by a TTL rule in new distributed file system

from the ConfigNetwork online interface
- to make this possible, a large refactoring and reorganisation of data structures was necessary
