DBIC Migrations

[osfameron]

Please review! If this, or something like this, gets merged in would also require

• documentation in fxmystreet.org etc.
• vagrant install script to use migrations
• travis build script to use migrations

Fixes #856

Documented in bin/migrate

A sample second migration is available in the migration-test-moderation
branch.

Alternatively, this may be overly baroque... I've updated bin/update-schema in 8758caf to do the documented on --commit, and to allow downgrades (from X to Y only, not multiple downgrades as yet) which may do for now?

Looks like it did do for now.
