- added many stack trace outputs for exceptions in crawl profile handler to find the 'missing profile handle' bug
- catched one more timeout exception in httpd file loader

if there are many concurrent server sessions, the timout is decreased.
This should avoid a situation where the clean-up thread is too
late to stop running http sessions that should be terminated
before the maximum number of server sessions is reached.

- extended the OAI-PMH test applet and integrated it into the menu. Does still not import OAI-PMH records, but shows that it is able to read and parse this data
- some redesign in ZURL storage: refactoring of access methods, better concurrency, less synchronization
- added a limitation to the LURL metadata database table cache to 20 million entries: this cache was until now not limited and only limited by the available RAM which may have caused a memory-leak-like behavior.

This is a major change in the organization of indexes.
Please consider a back-up of your data before you run this update.
All existing index files will be moved and renamed to a new position.
With this change, it will be possible to maintain different indexes for different purposes and it will be possible to have a distinction between DHT-in and DHT-out specific indexes. Tenants may also have their own index, and it may be possible to have histories and back-ups of indexes. This is just the beginning, many servlets must be adopted after this change, but all functions that had been there should still work.

*) refacored BlacklistCleaner_p.java for better readability
*) moved check of validity of patterns to the Balcklist implementation since patterns might be valid in one implementation, but not in another

This bug affected Tables in case that a removeOne() was called and a RAM copy of the table was active. It may happen for peer owners with a lot of RAM assigned to YaCy. The bug appeared especially during crawling when the balancer tried to get new entries from the crawl queue.
This bug may help to solve report at
http://forum.yacy-websuche.de/viewtopic.php?p=17417#p17417
and will be tracked there

to make this possible, the yacyURL must be able to process file:// urls, which has also been implemented
testing of the new class resulted in some bugfixes in other classes

- limit comparisment to only the first 10 elements that had been sorted before without IO
- added a size cache to index computation because the size is computed at least twice in set comparator

- added caption to maps containing latitude and longitude information
- prevented that maps occur on second search page
- added location names to did-you-mean

the must be downloaded manually by the user and placed in DATA/DICTIONARIES/source
for each externally imported dictionary file there will be a translator that converts the input file once
into a YaCy-internat data format.
Files that will be provided together with yacy releases may still be placed in <root>/dictionaries

- some redesign of DidYouMean that was necessary to follow
a special rule how a library should be used:
- the library provides words that start or end with a test
word which may be possibly also an empty set of words
- all words that the DidYouMean produced with the four
production rules are used to generate a set of
library-completed words
- if this process results in any words from the library,
only library-genrated words are taken
- if the is no library-generated word at all, take the
artifial generated word
- all words that result from these rules are tested against
the index
- the result is ordered using a lightweight comparator that
prefers short words
- a not-so-much-io test against the index is beeing prepared
next
- insered the library initialization into the switchboard

which can be used by any other classes to support their functions.
libraries are designed in such a way that users can create and
insert their own library files, but can also be imported from
other sources. As an example the "Korpusbasierte Wortgrundformliste
DeReWo des Institut für Deutsche Sprache" from
http://www.ids-mannheim.de has been integrated. This dictionary
is licensed to be used for all non-profit purposes. In case that
YaCy is used for commercial uses, this library must be removed.
The new library provilder reads the original source and translates
it into a simple word list to be used for the did-you-mean library
provider. More libraries may be provided in the future using
a download-servlet which puts files from the internet into the
<application-root>/dictionaries/ path.

- less pages are fetched in advance

this will cause better computation speed for single- and multi-core;
there are enhancements that will speed up old and slow machines as well
as multi-core CPUs. Indexing of surrogates has been speed up
from 4000 PPM to over 20000 PPM on a simple dual core office computer.
Since the enhancements are mostly in core routines, the hack should also
speed up search performance.

- added a open-on-demand hack to heap files: when a heap file is
opened the first time, it is first scanned to get a key index
and then it is closed again. This will free up file pointers
in cases where a really large number of blob files are opened
upon initialization of ArrayStack objects. This should solve
also a problem reported in

this is the beginning of some architecture changes that will hopefully bring some more stability, speed and transparency to the search process.

- check routine at the beginning of the import of table keys that check that all imported keys are well-formed. All records that have a ill-formed key are deleted. This is a hack and is not tested since I don't have bad data here to test with. If the effect is seen in the wild, please report in the forum.
