Upgrading from an old QC

Apparently the QC database schema has changed a bit since I last updated. Below is the diff of my db/structure.sql after running `QC::Setup.drop; QC::Setup.create` locally. Is there a better way to migrate the production database short of hand-coding the `UPDATE TABLE` query?
