If an extension has been updated, and the table schema has changed, we want to run django-evolution to migrate the database forward.

As stated above, for this patch, I'm relying on revision 3 of http://reviews.reviewboard.org/r/1633/ .  It's still not clear how django-evolution should be changed to support this type of programmatic invocation.  This is my first go at it - let me know if you have any ideas.

Manual.  Works just fine.
