Title: Fixed: popoverDidShow in Firefox. New: popover animation support in Firefox, Opera and IE10.

Before this fix, popoverDidShow: would not be sent to popover delegates when
the app ran in Firefox due to Firefox now recognising the -webkit-transition
property, but not the webkitTransitionEnd event.

Also, before this fix popover animation was only implemented for Webkit based
browsers.

This fix resolves that issue and in addition adds full support for animated
popovers in all browsers that support CSS transitions. The fix also improves
Cappuccino's general support for CSS3 animations.
