Adopt a Forum

Browse Source 
* Forums are disowned on user account deletion (their owner_id=0)
* A forum without an owner shows a notice at the bottom with a link to petition
  to adopt the forum. It goes to the Contact form with a special subject.
  * Note: there is no easy way to re-assign ownership yet other than a direct
    database query.
* Code cleanup
  * Alphabetize the DB.AutoMigrate tables.
  * Delete more things on user deletion: forum_memberships, admin_group_users
  * Vacuum worker to clean up orphaned polls after the threads are removed
