Make migrations use transaction and rollback if something was wrong

Reported by Ian Bailey | August 14th, 2008 @ 07:58 PM | in 2.x

When a migration is running and an error is raised, everything before the error is applied to the database schema and everything before (obviously) doesn't. Also, the migration version is stored as executed, which creates schema inconsistency and migration version control brokeness.

This would not work for migrations involving schema changes on databases that do not support DDL rollback (i.e. MySQL, Oracle).
