Switch DB migrations from SQLAlchemy-migrate to Alembic

Registered by David Ripton

SQLAlchemy-migrate is fine for straight-line migrations, but does not really support branching, needed for clean backports of some but not all migrations to a stable branch. Alembic has better branching support and will meet our needs better. We should switch migration frameworks, and convert our existing migration scripts to Alembic syntax.
