Dave Page d63b54610b Move the config database schema version out of the configuration file and into the model class.
Turns out using the config file isn't a good idea if users copy config.py to config_local.py, as it prevents upgrades to the database. This has the added side-effect of simplifying future changes, as you only need to edit 2 files to modify the config DB now, not 3.
