eb12e15738 moved all Double values to Float values because of
http://www.exploringbinary.com/java-hangs-when-converting-2-2250738585072012e-308/
YaCy does not really need double-precision floating point computation anywhere, so this should not affect any feature

a9f754c45f removed unused CR accumulation and distribution process
this was never used and extended in the last years. The resulting YBR ranking criteria
is still a good idea and will be used in the future. Possible generation methods for YBR
ranking are:
- "trust-rank" using the link structure as can be discovered in a single crawl (idea from FSCONS)
- "block-rank" calculated from the local link structure
- a distributed "block-rank" using the xml API to the link structure from other peers

- better abstraction of ordering technique
- fixed some bugs according to result numbering (distinguish different counters in Queue)
- fixed a ordering bug in post-ranking (ordering was decreased instead of increased)
- reversed ordering numbering using a reversed ordering. The higher the ranking number the better (now).

5a994c9796 added a scheduler based on API actions
- every process that is monitored with the API Steering interface can now be scheduled!
- added input methods in Steering interface to set a scheduling time
- added a view on the steering api that shows only crawl jobs inside the Crawl Profile servlet
- added a scheduling call process in the cleanup process handler that triggers the scheduled processes
This causes that the cleanup now also looks for scheduled processes. Such processes are therefore not executed at
the same time as given in the target execution time but they will be executed within the cleanup process time window.

22dbbcfa56 better (and corrected) recognition of intranet and internet-addresses. This corrects the isLocal property that is used by network definitions to restrict index ranges to local and global addresses. Address locations (intranet or internet) had been partly identified by the top level domain of the host address. Since intranet addresses can also be addressed using a host name that is in a country domain it is necessary to do a dns resolving for each check. The check is supported by a local dns cache so the intranet/internet check should not affect network traffic too much. To ensure that the cache works properly the cache class was upgraded to better concurrency data structures.

b6fb239e74 redesign of parser interface:
some file types are containers for several files. These containers had been parsed in such a way that the set of resulting parsed content was merged into one single document before parsing. Using this parser infrastructure it is not possible to parse document containers that contain individual files. An example is a rss file where the rss messages can be treated as individual documents with their own url reference. Another example is a surrogate file which was treated with a special operation outside of the parser infrastructure.
This commit introduces a redesigned parser interface and a new abstract parser implementation. The new parser interface has now only one entry point and returns always a set of parsed documents. In case of single documents the parser method returns a set of one documents.
To be compliant with the new interface, the zip and tar parser had been also completely redesigned. All parsers are now much more simple and cleaner in its structure. The switchboard operations had been extended to operate with sets of parsed files, not single parsed files.
additionally, parsing of jar manifest files had been added.

37b8827a7a - removed the UPnP library sources from sbbi and added the jar library again. The library was included to get support for fedora releases, but after this time the fact that the sbbi cannot be part of fedora should be re-discussed. If this will still not be possible, then we may integrate the sbbi UPnP package using reflection.
- cleaned uo the code. The new eclipse helios provided new warnings for dead code. This change cleans up most of these warnings

4cd5418963 removed finalize methods because of a hint in
http://java.sun.com/javase/6/webnotes/trouble/TSG-VM/html/memleaks.html#gbyvh

The finalize method prevents that the memory, used by the objects containing the finalize method, is collected and available for the garbage collector. Instead, the memory allocated by such classes are enqueued to a java-internal finalize queue runner. This slows down all operations that uses a lot of object containing finalize methods.

this fix does not remove all finalize method, but such that may be used for throw-away objects that are allocated many times. This should cause a better run-time performance and less OutOfMemoryErrors
