Refactoring templates, bug sync and database to fit with new FreezeException nomenclature
adding alembic upgrade script for db changes
updated bug_sync code for python-bugzilla >= 0.8
Testing
I've done several syncs on both sqlite and postgres dbs and clicked around to make sure that all the templates that _were_ working are still working. Some of the admin pages still have issues but that is orthogonal to the changes here.
I did an alembic upgrade of the database with no issues.
