for indexing, the plasmaWordIndex.
The new data structure is ready-to-use, but currently disabled.
It can be activated by setting the static
plasmaWordIndex.useCollectionIndex
to true. This shall be done for testing purpose.
The new index is stored to
DATA/INDEX/PUBLIC/TEXT
The directory PLASMA shall be used only for crawler in the future.
Attention: during testing the data structure in INDEX may change,
and created indexes with the new data structure may get useless.

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.

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 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.

@Martin: bitte schaue mal warum die Variablenzuweisung
in plasmaCrawlNURLImporter war. So wie sie waren, waren sie überflüssig.
Das hattest du dir bestimmt nicht so gedacht.
Sollten es ggf. globale Variablen sein?

- restructuring to allow different import tasks to be controlled via one gui
- adding possibility to import a single assortment file
- adding possibility to set the cache size that should be used
