Merge lp:~abentley/charmworld/remove-018-migration into lp:~juju-jitsu/charmworld/trunk

[Aaron Bentley]

Remove 018 migration; before an exodus and already deployed to production.

Remove the 018 migration so that deployment is possible.

The 019 migration is an exodus, so no migrations are permitted before it. This currently blocks new deployments.

433. By Aaron Bentley on 2013-10-25
