	Fix crash on multihead setups, when closing a window. The active
	window and previously active window are generally the same for all
	screens (since there's only one focus), and they could be invalid for
	one screen in some cases.
	Fix bug #447387

	* libwnck/screen.c: (wnck_screen_finalize): remove weak pointers
	(set_active_window): new, remove the weak pointer on the old active
	window and set a new weak pointer to the new active window so that our
	variable is reset to NULL when the active window is destroyed
	(set_previously_active_window): ditto for previously active window
	(update_client_list): use new functions, and first check if the closed
	window was previously active window (else, it could have been the
	active window, and then previously active window, which was wrong)
	(update_active_window): use new functions
