watchdog error

themekey_base.inc at line 449:

watchdog('php', 'ThemeKey map function %map_function does not exists', array('%map_function' => $map_func), 'error');

should be

watchdog('php', 'ThemeKey map function %map_function does not exists', array('%map_function' => $map_func), WATCHDOG_ERROR);

And maybe another check is needed in every file to change every 'error' to WATCHDOG_ERROR.
