- moved all url and index(RWI) entries to index package
- better naming to distinguish RWI entries and URL entries

- added test migration method to migrate the old LURL to a new LURL
the new LURL will be splitted into different tables for each month
this solves several problems:
- the biggest table in YaCy is splitted in different parts and can
also be managed in filesystems that are limited to 2GB
- the oldest entries can easily be identified, used for re-crawl und
deleted
- The complete database can be limited to a specific size (as wanted many times)

- added generation of a compressed index within remote peers during global search
- added selection of specific urls within remote peers during secondary global search

to store the index entry. This is another step to move to the new database structure.
A side effect of this change is, that index storage uses much less RAM space,
which affects the index RAM cache.

indexContainers from RAM must be cloned explicitely to prevent
side-effects on stored indexContainer objects in Cache
* changed behaviour of urlReference deletion from indexContainers:
deletion does not user retrieval of all Elements from the assortments
* added textual configuration of kelondroRow and kelondroColumn definition
* update of kelondroRow usage in yacyNews
* modified kelondroAttrSeq to use modified kelondroColumn parser

an iteration of key elements in kelondroTree databases is no longer supported.
this is now replaced by an iteration of kelondroRow.Entry objects from the database
Iteration of keys from the database was mostly followed by retrieval of the row
from the database, whcih caused unnecessary database load.
The index selection was also redesigned to use the new row iteration methods.
This affects many funktions, most important is the DHT selection routine which is now much faster.

* mainly for the transition to the new indexing database structure
* a bugfix for an endless loop inside kelondroTree iteration
* a bugfix for bulk read inside a kelondroTree iteration; the bug caused that some elements had been iterated twice
* very strong speed enhancement for url/domain extraction

This shall be seen as an experiment to exclude all cases where
there could be a DNS lookup during URL comparisment.

This was done because the wordHashes iterator will get another integer
parameter and then conflicts with the wordHashes set generation

The cache will fill up and flushed explicitely when it is full.
This shall remove double-access of assortments (indexing and flush)
during indexing process. Hopefully this should reduce IO.
The main idea is: the cache shall mainly be flushed by DHT transfer, and
only indexes that shall be hosted by the own peer are flushed to the
assortments. This needs further work.

- changed index collection process: indexes are not first flushed to indexEntity,
but now collected directly from ram cache and assortments

- replaced usage of temporary IndexEntity by EntryContainer
- added more attributes to word index
- added exact-string search (using quotes in query)
- disabled writing into WORDS during search; EntryContainers are used instead

- implemented hand-over of new word index attributes during remote search
- implemented word-distance computation during search

(no more NULL values are returned, instead, an IOException is thrown)
- removed ugly damagedURLS implementation from plasmaCrawlLURL.java
(this inserted a static value into the Object which is not really a good style)
- re-coded damagedURLS collection in yacy.java by catching an exception and evaluating the exception message
to do:
- the urldbcleanup feature must be re-tested
