Add 5/12 - 7/12 two uneven column style

Patch applies successfully, but needed to run updb after applying. I think we need an update hook for this.

This is a great example of how this module can be altered. There hasn't been any other requests for this, so we've decided to not include it in the module, but thank you for the code, it will be here if anyone else needs it!

Marking as fixed so contributors get issue credit.
