11188cd7eb resource observer now uses the Java 6 method to check for free space. thus, disk observing now needs Java 6 installed.

8ce936bcdd added an api recording function: it shall be possible to record 
all operations on YaCy in a database that should make it possible
1) to re-create a setting on fresh peers
2) to transmit a setting from one peer to another
3) to re-create crawl starts after a complete deletion of the index
This functionality will also support
4) scheduled re-crawls (new implementation)
To implement this, a new database structure has been crated that stores maps into blob heaps. to encode maps the b-encoding technique was used (this is the same encoding that torrent files use)
- added a b-encoder
- enhanced the b-decoder
- added a b-encoded map heap data structure
- added a table organisation based on b-encoded heaps
- added a servlet to maintain such tables (see Tables_p.html)
- integrated the servlet into the Advanced Settings menu
- added an api recording based on the new tables

18172451a0 better search computation: 
- increased sort limit, now 3000 entries, before: 1000
  this should cause that more results can be shown in case
  of strong limitating constraints, like domain navigation
- enhanced the sort process
- check against domain navigator bugs
- fix in sort stack
- showing now all naviagtion pages at first search (not only next page)

4a5100789f replaced _all_ size() == 0 with isEmpty() and all size() > 0 with !isEmpty(). The isEmpty() method is much faster in some cases, especially when used to access badly balanced hashtables where an size() operation becomes a large iteration.

4df88a4e7a - fixes for missing or bad hashCode computation

fd0658ce7c avoid forced execution of InetAddress.getLocalHost() at startup, because that hangs at some strangely declared linux configurations. The Domains.localHostAddresses object is first instantiated with a more simple logic and enriched with more host addresses using a concurrent thread that will not block a startup process.
