Allow population of signoff specs with SVN commit messages

This pulls them from the latest SVN commit on trunk. We don't have a
failproof method of getting the exact right commit, but this should be
close if it is run on a regular basis via cron (aka hourly).

Note that running locally, I needed the development version of South to
get the migration included here to apply because of information_schema
changes in the current version of MySQL.
