This change is inspired by the need to see a network connected to the index it creates in a indexing team.
It is not possible to divide the network and the index. Therefore all control files for the network was moved to the network within the INDEX/<network-name> subfolder.
The remaining YACYDB is superfluous and can be deleted.
The yacyDB and yacyNews data structures are now part of plasmaWordIndex. Therefore all methods, using static access to yacySeedDB had to be rewritten. A special problem had been all the port forwarding methods which had been tightly mixed with seed construction. It was not possible to move the port forwarding functions to the place, meaning and usage of plasmaWordIndex. Therefore the port forwarding had been deleted (I guess nobody used it and it can be simulated by methods outside of YaCy).
The mySeed.txt is automatically moved to the current network position. A new effect causes that every network will create a different local seed file, which is ok, since the seed identifies the peer only against the network (it is the purpose of the seed hash to give a peer a location within the DHT).
No other functional change has been made. The next steps to enable network switcing are:
- shift of crawler tables from PLASMADB into the network (crawls are also network-specific)
- possibly shift of plasmaWordIndex code into yacy package (index management is network-specific)
- servlet to switch networks

- changed isLocal Property in such a way that it is possible to see if a domain is in the internet (and not intranet)

- fix for handling of collection index that appears when removing elements
- added another navigation method (stub, not working yet)

- separated sidebars in new search interface and placed them in their own files
which can be put in into the search page like plug-ins

- refactoring of plasmaParserDocument to use Dublin Core - compatible property names
- redesign of url handling in parser and condenser (less String-to-yacyURL conversion)
- more generics

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

search profiling showed, that a major amount of time is wasted by computing url hashes. The computation does an intranet-check, which needs a DNS lookup. This caused that each urlhash computation needed 100-200 milliseconds, which caused remote searches to delay at least 1 second more that necessary. The solution to this problem is to attach a URL hash to the URL data structure, because that means that the url hash value can be filled after retrieval of the URL from the database. The redesign of the url/urlhash management caused a major redesign of many parts of the software. Since some parts had been decided to be given up they had been removed during this change to avoid unnecessary maintenance of unused code.
