    SQL scripts should not manage transactions

    Glance SQL scripts assume too much about the environment and the way in
    which they are executed by sqlalchemy-migrate. Particularly, they manage
    transactions on their own even though sqlalchemy-migrate do it itself,
    plus it assumes that scripts are executed in one go (even though
    standard Python DB-API 2.0 does not mention multi-statement SQL commands
    to be executed on DB cursors.

    Also fix comments to be actual SQL comments and not C comments
