1.1.0.beta12

Changelog

• Write default BLAST options that were previously defined only in the code
  to config file during setup. Since old config files won't have this info
  available, retain the old behaviour of automatically adding '-task blastn'
  to BLASTN searches and log this during startup.
  (issue raised by Niek Art)
• Multipart database volumes can have 3 digit suffixes (e.g.
  refseq_genomic.100). Our regex allowed for only 2 digit
  suffixes (e.g. nr.00). Fixed that.
  (issue raised by Niek Art)
• Show location of config file by default during startup
• Code-style improvements.
