2.0.0.rc5

1. Running sequenceserver -m will now automatically detect older V4 databases, and those created without the -parse_seqids option of makeblastdb, and offer to rebuild them. This works even if you deleted the original FASTA files. Database titles are preserved when rebuilding, however, taxonomy information in the database is unfortunately not preserved.
2. BLASTing a mix of older V4 and newer V5 databases causes error. SequenceServer now catches and informs the user of this error. Thanks to Massimiliano babbucci for reporting this issue.
3. The list of databases in the search form should be alphabetically sorted. This behaviour was lost in the rewrite leading to version 2.0 and has now been fixed. Thanks to Loraine Guéguen for reporting the issue.
