	* libgimpwidgets/gimpbutton.c: massively simplified. Don't fiddle
	in GtkButton's internals (like setting "in_button" and forcing
	redraws). Instead, simply remember the modifier state in
	button_press() and check it in clicked(); if the state is != 0,
	stop the "clicked" emission and emit "extended-clicked" instead.
