* gdesktop.c: We are now using the new desktop icon code.  It is
	not yet complete, but what is there does work.  We have icon
	creation, auto-layout and snapping.  Next step is drag and drop
	and popup menus.

	* glayout.c: #ifdef out the stuff that uses the old desktop code.
	I will replace it gradually.
	* gmain.c: Likewise.
	* gscreen.c: Likewise.
