* Simplified db controller permissions options The existing objects were confusing because they did the same thing as setting permissions to true, but gave the impressions that something special was happening/required. * Added DB Backup Integration Role This will allow us to assign certain api_keys this role, in order to automate db backups * Allowed admin api_keys to have configurable roles This will allow keys for the admin api to do customised things such as db export * Added ghost-backup integration to fixtures * Added migrations for DB Backup Integration and role
