[damagecontrol-dev] Warning: big database refactoring

[Aslak Hellesoy]

For those of you who are running DC off SVN HEAD
(damagecontrol_active_record branch, which is essentially the trunk):

The next commit will have some database refactorings that shuffle
revision history data around.
After this update you *must* do a 'rake migrate'.

Everything *should* work fine, but make a backup of your database
before you migrate in case I didn't test the migration well enough.
