Designed a frontend for task filtering. As it is it should work on most browsers(except IE 6 and down). On IE9+ Chrome 2+(i think) and Firefox 4+ it has full support(effects & stuff).
This is a patch in preparation for the ajax task filtering(which should work on old browsers but requires javascript).
