- 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

because of the strongly enhanced indexing speed when using the new IndexCell RWI data structures (> 2000PPM on my notebook), it is now necessary to control the crawling speed depending on the response time of the target server (which is also YaCy in case of some intranet indexing use cases).
The latency factor in crawl delay times is derived from the time that a target hosts takes to answer on http requests. For internet domains, the crawl delay is a minimum of twice the response time, in intranet cases the delay time is now a halve of the response time.
- added API to monitor the latency times of the crawler:
a new api at /api/latency_p.xml returns the current response times of domains, the time when the domain was accessed by the crawler the last time and many more attributes.

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.

The speed of the kelondro indexing class ObjectIndexCache can be compared with Javas standard TreeMap with the main method in IntegerHandleIndex. The result is, that the kelondro indexing needs only 1/5 of the memory that TreeMap uses! In exchange, the kelondro classes are slower than TreeMap, about four (!) times slower. However, this is not so bad because the better use of the memory is a strong advantage and makes it possible that YaCy can maintain such a large number of document (> 50 million) in one peer.

without an order by the primary key. The result is a very fast enumeration of the Eco table data structure. Other table data types are not affected.
The new enumerator is used for the url export function that can be accessed from the online interface (Index Administration -> URL References -> Export). This export should now be much faster, if all url database files are from type Eco
The new enumeration is also used at other functions in YaCy, i.e. the initialization of the crawl balancer and the initialization of YaCy News.

- fixed a display bug for the performance graph
- fixed deadlock when initialization of awt happens simultanously
- removed some debugging output

- balancer writes cause of robots.txt in log file for crawl delay
- removed log output for forced GC
- smaller RAM flush for RWI cache, should cause more usage of cache and faster crawling

- fixed a bug with merge method
- patched wrong output of language identification (not fixed, only patched!)

- reduced maximum number of error url references to save some memory (this was actually a small memory leak)

- added automatic time delay in case that a large number of urls come from the same domain
- added additional time delay in case that an url is a dynamic (CGI) url. This shall cause less IO on targets

- fixed parsing of crawl-delay statements when seconds were given with float numbers
- enhanced performance of profiling (not too many loggings; not more than one per second)
- removed some debug output
- fixed wrong return type in logging
- added a logging condition in httpd to prevent that logging statements are generated when they are not written (should be added everywhere!)
- fixed wrong word distance computation in RWI management

- 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)

- no more keep-order parameter in remove (it was not possible to make this strict, and not useful)
- some small enhancements in balancer
- robots parser without references in switchboard
- changes synchronization in robots
