* gdk/SimpleEvent.cs : Temporarily comment the GCHandle code until
	a layout is ready and exceptions can be avoided.
	* gtk/Widget.cs : Killed all the signal and event attaching methods.
	They never belonged here, and now they exist in the SimpleEvent.
	Add a Signals hash to hold refs of the Signal handlers. Killed default
	ctor and the dtor.  The event Add/Remove methods now create a
	SimpleEvent, stuff it in the hash, and remove it when the last handler
	disappears.
