Configure the database backend in the config.ini The database backend is currently configured in the 'db/backend_name' file which is just another file that needs to be configured when setting up or migrating a tracker instance. By moving this setting into the config.ini it helps to reduce the number of files that need to be configured and is more logical place for users to find the setting.
