* All tools now have a longer description in the tool-specific help
  page.
* Arguments are now presented in groups and the order is the same
  across tools.

Furthermore:
* Fixed bug that rendered BGHomStats and BGEstimate with the -H
  option useless.
* The report of Allelefinder and BGEstimate is now written to
  sys.stderr by default. This means the report is now always
  generated (but it may be sent directly to /dev/null explicitly by
  the user). The big plus is that the progress of the tools is
  visible in the terminal when the tools are run by hand.
