Subject: Migrate version to use snakeoil's format_version() to append git commit info.
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=b8ce8e8cdcae5e40712f7972a46e5ff04cfcb95d;p=catalyst.git

Migrate version to use snakeoil's format_version() to append git commit info.

This will make tagging releases easy as well as providing better debug info while running live versions of the software.
