Since the interface language defaults to IP geolocation by google, the default language is now set to english. Still not sure if this is the best solution, but at least temporarily should clear up some confusion for users with instances deployed in countries outside of their own. Also performed some minor cleanup: - Updated name of strip_blocked_sites to clean_query - Added clean_query to list of jinja template functions - Ensured site block list doesn't contain duplicate filters
