-fix bug in cache for atlas import/export -fix some menus -fixed bug in out transition curves -detect and remove file:/// in collada -remove multiscript for now -remove dependencies on mouse in OS, moved to Input -avoid fscache from screwing up (fix might make it slower, but it works) -funcref was missing, it's there now
