- the index administration now uses the same code base for url selection and collection
as the search interface. The index administration is therefore a good test environment for
ranking order control
- removed old postsorting-algorithms, will be replaced with new one
- fixed many bugs occurred before during ranking; especially the contraint filtering method
removed too many links
- fixed media search flags; had been attached to too many urls. The effect should be a better
pre-sorting before media load within snippet fetch

to do this, the index administration interface was extended.
It is now possible to select parts of a index.
See properties shown in interface after a word search for details.

- enhanced searchtime in kelondroRowSets
- enhanced uniq() - reverse enumeration causes less time in case of mass removal of doubles

the enhancement was made by using better organized data structures and
multi-threading during the sort. A sort can be divided into two separate
processes when the first partition of the quicksort algorithm was done.
Generating a separate thread and starting the thread takes only 10 milliseconds,
so using a separate thread makes only sense if the data amount is large.
statistics about the speed-up:
without ehancement: 250 milliseconds for 100000 entries
with data structure enhancement: 170 milliseconds for 100000 entries
with additional second thread (if second processor is present): 130 milliseconds.
For dual-processor systems, this means about 100% speed-up
a test can be made with the following command:
java -classpath classes de.anomic.kelondro.kelondroRowCollection

- before absolute paths would be expanded incorrectly, e.g.: fooPath=/a/b/c would become /path/to/yacy/root/a/b/c. Now you can put nearly every dynamically generated data with a configurable path to a location outside of yacys root dir without having to use symlinks (probably good for third party distribution packaging).
- abstractServerSwitch.getConfigPath(setting, default) returns a File instance, either with an absolute path or relative to the applications root path.
- exceptions (hardcoded):
DATA/LOG/yacy.logging
DATA/SETTINGS/httpProxy.conf
DATA/SETTINGS/user.db
TODO: all of these are the global configuration files and they should probably be put into _one_ command line configurable settings path, so it would be possible to package them in /etc/ for example.
- add missing workPath to yacy.init (it was used in code, but there was no default in the file)
- fix broken skinPath (was skinsPath in yacy.init but skinsPath in the code) + a few other broken config reading caused by typos.
- replaced path setting names and their default values with the related static fields in plasmaSwitchboard where not already done/existing

- Test wCacheMaxChunk against maxURLinCache(), not getMaxWordCount(). This triggered a flush everytime dhtFlushControl() was called.
- If triggered, flush at least 1 entry.

- final flush only when tabletype = RAM
- prestacker (dns prefetch) only if tabletype = RAM and busytime <= 100
- number of maximun entries in stacker is configurable in yacy.init (stacker.slots)

two main changes must be implemented to enable mass remote crawls:
- shift control of robots.txt to crawl queue (away from stacker). This is necessary since remote
crawls can contain unchecked urls. Each peer must check the robots to prevent that it is misused
as crawl agent for unwanted file retrieval
- implement new index files that control double-check of remotely crawled urls
After removal of robots.txt checking from stacker threads, the multi-threading of this process is void.
Multithreading has been removed. Also the thread pools for the crawl threads had been removed, since
creation of these threads is not resource-consuming, for a detailed explanation see svn 4106

- update PDFBox package to current version 0.7.3
- use new security model in PDFBox to "guess" wether we can decrypt a document or not
NOTE: When upgrading to this version make sure the old PDFBox-0.7.2.jar is removed from libx/

It seems improbable, but it might happen, that during a crawl all queues (indexing, crawling, ...) except the crawl URL stacker ran empty. This commit adds an additional check for an empty crawl stacker queue before executing the profile cleaner.

in extreme situations this will cause that no remote crawls are send out any more
this is bad, but it protects the case where failing remote crawls fill up the local queue too much,
which is even worse

Note: the new DateFormatter822 in the plasmaSwitchboard is just a copy of the DateFormatter that always uses the US locale to allow formatting of a loocale independent date String.

and replaced old fist hash computation by new method that tries to find a gap in the current dht
to do this, it is necessary that the network bootstraping is done before the own hash is computed
this made further redesigns in peer initialization order necessary
