ARB change log

Fixes for arb-6.0.1 (22 Jul 2014):

 - arb_parsimony
   - skip unwanted automatic branchlength recalculations (e.g. by unfolding a group)
   - corrected branchlength calculation for "Add marked partial species"
   - dots were treated as gaps for protein sequences (now treated as 'X'; analog to DNA treating gaps as 'N'). thx to Yan Shi for detecting that problem!
 - print
   - preview failed (showed empty postscript file)
   - print to file now always saves in user home
 - raxml (import tree with bootstrap values)

Major changes for arb-6.0 (4 Jun 2014):

 - merge databases allows to
   - merge from an existing database into the database loaded in ARB_NT
   - merge to existing databases from the database loaded in ARB_NT
 - ARB can now
   - be restarted with another database and
   - a second instance of ARB can be opened
 - ARB_DIST
   - Detect clusters of species with similar sequences (OTUs)
   - allow automatic recalculation of matrix and/or tree whenever some parameter or
     data changes (only makes sense for smaller species sets)
   - extract distance matrix from tree
 - Rewrote chimera check. Allows filtering
 - added RNACMA (computes clusters of correlated positions)
 - PT-Server
   - changed behavior
     - no longer report less hits for a part of a probe than for the probe itself (occurred at 3'-end of alignment)
     - reports previously missing hits in joined genes
     - reports more hits at 3'-end of alignment (when using mismatches the PT-server now reports possible
       matches that go beyond the end of the sequence)
     - dots in the middle of the alignment act like the sequence ends there
     - minimum probe length reduced to 2 (was 6)
     - allow up to 50% of probe to mismatch
   - performance
     - optimized memory-estimation (will build in fewer passes)
     - uses any number of passes (not only 1, 5, 25, ...)
     - allows to define used memory by setting environment variable ARB_MEMORY
     - reduced memory needed to build/run ptserver (approx. 50%)

     - allow to design probes with different lengths (specifying min/max length)
     - fixed number of outgroup hits reported when decreasing temperature
       (now each outgroup member only occurs once)
     - show possible reasons why no probes could be designed
   - probe match (allow any number of mismatches)
   - next relative search
     - can be restricted to column ranges (needs a PT-Server calculated from aligned sequences)
