initial.rev3

-changed PanelUI-profilist a class rather than id
-added advanced button
-leraned that PUIsync doesn't initialize till first time menu is opened,
so added the init into the popupshowing of PanelUI-profilist
-Also use boxObject to get height rather than getComputedValue,
boxObject height is 0 when PUIsync hasn't been initalized yet
-added in on the mouseenter (and mouseleave) if lastChild of hbox is
disabled then forget anim, I added this because when go into customize
mode things should disable
