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.

topics will now only be computed using the document title, not the document url,
because the host navigator is now responsible for statistical effects of urls.

- fixed too early computation of navigation
- moved navigation rendering to yacysearchtrailer
- added more asserts

- moved some servlets from here to there..
- changed menu structure
- removed yacyui-portaltest.html which contained an example for the live search which is now integrated on all pages in yacy. The code snippet example from that page is integrated into the ConfigLiveSearch.html servlet

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.

- refactoring: migrated data objects for the new connector classes
- added a DAO interface class to specify an abstract interface for database retrieval connector methods

- after a search is started, it is analysed how many hits are in each site
- this can be done really efficient, because the navigation information is hidden in the url hash and can be computed very fast
- the search result shows a column on the right with the hosts and the hits per host
- after a click on a host the search is modified using the efficient site: - operator

- 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

terms (words) are not any more retrieved by their word hash string, but by a byte[] containing the word hash.
this has strong advantages when RWIs are sorted in the ReferenceContainer Cache and compared with the sun.java TreeMap method, which needed getBytes() and new String() transformations before.
Many thousands of such conversions are now omitted every second, which increases the indexing speed by a factor of two.

- during index joins all word positions are maintained: better ranking for word distance possible; exact phrase match can be implemented soundly

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
