fixed analysis_capacity for ktreedist + multifurcation nodes in MakeSpeciesTree
added composite index for seq_member_id and gene_member_id to speed up joins from seq to gene (useful for retrieving large bacterial families)
bugfix: nobody knows why it used to work, but with newer version of Perl it doesn't - so make it work again
allow the config to redefine both "release" and "prev_release" numbers, or take them from databases
The patch does not account for NULL chr_names
Transcripts on patches may have negative coordinates
