* updates:
* 04.19.04 fixed cascade problem with menus nested greater than two levels.
* 12.23.03 added hideCurrent for menu actuators with no menus. renamed to TransMenu.
* 04.18.03	fixed render bug in IE 5.0 Mac by removing that browser from compatibility table ;)
*			also made gecko check a little more strict by specifying build no.
