again, this is a change against 4.2 branch
I haven't established any performance increase with this change yet,
but it still seems like a good idea to remove the
mouseEnabled=true hack that we had put in place before.

Summary: fix for swf9 context menus, mouseEnabled no longer always set
to true on every sprite

Details:
+ To work around the original bug (context menus don't work when
mouseEnabled == false on any parent), I created a context menu at the
very top level of the sprite hierarchy. This menu is the only context
menu in the entire application that is active. This is ensured by
having a "right-click-trap" sprite as the immediate child , that has
mouseEnabled = false.
The Laszlo app canvas sprite and its children are children of this
'right click trap' sprite.
+ the onmenuopen event on the active contextmenu is forwarded to the
appropriate view's menu , giving the view a chance to dynamically set
items when menu is opened
+ mouseEnabled is once again false by default for views, and is only
set to true for clickable views. This should hopefully help with the
CPU usage problem.
