Javi Martín df959b74f6 Make migrations reversible
While I don't use this feature, there are developers who do. It's useful
when running migrations and changing branches.

I'm raising an `ActiveRecord::IrreversibleMigration` exception in every
`drop_table` migration because these migrations were all done before
version 1.0.0, and so making all of them reversible would be too much
work for little benefit.
