* Add guid to sql so that array_diff will work

 * Fix error raising in query
 * Fix destruct in app and orm
 * event trait fire will return true/false depening on if it should be cancelled or not
 * App::get_url added
 * App error event will pass request/response
 * App handle event can cancel normal handle
 * App error event can cancel normal onerror
