	Work to make clicking on an inactive window not focus it if the
	click subsequently starts a drag. Fixes bug 1681, and removes
	fixme bugs 5030, 5032, and 5033

	* libnautilus-extensions/nautilus-drag-window.c,
	libnautilus-extensions/nautilus-drag-window.h
	(nautilus_drag_window_register): new module, hooks into a
	GtkWindow to retrofit a focus policy that makes sense with drag
	and drop sources. When dragging from a window, a button press
	event that subsequently causes a drag to be started doesn't
	focus (or raise) the window

	This uses a sawfish-specific WM_PROTOCOL to handle the `don't
	raise' part (_SAWFISH_WM_RAISE_WINDOW), but everything else
	should work with any ICCCM-compliant wm. (The sawfish specific
	part will have zero effect with other wm's. It currently
	requires a cvs version of sawfish)

	* src/nautilus-window.c (nautilus_window_constructed):
	* src/nautilus-property-browser.c
	(nautilus_property_browser_initialize):
	Call nautilus_drag_window_register () on the window, since it
	may be used as a drag source

	* libnautilus-extensions/nautilus-gdk-extensions.c,
	libnautilus-extensions/nautilus-gdk-extensions.h
	(nautilus_gdk_window_focus,
	nautilus_gdk_window_set_wm_protocols): new functions
