- removed migration code
- removed BLOBTree
after the removal of the BLOBTree, a lot of dead code appeared:
- removed dead code that was needed for BLOBTree
Some more classes may have not much use any more after the removal of BLOBTree, but still have some component that are needed elsewhere. Additional Refactoring steps are needed to clean up dependencies and then more code may appear that is unused and can be removed as well.

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.

- after a index selection is made, the index is splitted into its vertical components
- from differrent index selctions the splitted components can be accumulated before they are placed into the transmission queue
- each splitted chunk gets its own transmission thread
- multiple transmission threads are started concurrently
- the process can be monitored with the blocking queue servlet
To implement that, a new package de.anomic.yacy.dht was created. Some old files have been removed.
The new index distribution model using a vertical DHT was implemented. An abstraction of this model
is implemented in the new dht package as interface. The freeworld network has now a configuration
of two vertial partitions; sixteen partitions are planned and will be configured if the process is bug-free.
This modification has three main targets:
- enhance the DHT transmission speed
- with a vertical DHT, a search will speed up. With two partitions, two times. With sixteen, sixteen times.
- the vertical DHT will apply a semi-dht for URLs, and peers will receive a fraction of the overall URLs they received before.
with two partitions, the fractions will be halve. With sixteen partitions, a 1/16 of the previous number of URLs.
BE CAREFULL, THIS IS A MAJOR CODE CHANGE, POSSIBLY FULL OF BUGS AND HARMFUL THINGS.

- added hash to HTCACHE storage files which will make it possible to join separate caches by just copying files

- removed the now superfluous HT storage thread
- reduced number of file decompression by shifting the compression moment to the future

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

- 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

A large refactoring was neccessary
- added another crawl start option: automatic restriction to sub-path
- removed crawlStartSimple and renamed crawl start expert
to crawl start (without expert)
- some changes to texts in crawl start
- added some more deletions when an web index is deleted:
delete also queues and robots cache
