make one of the toolbar buttons lock up the demo

2002-04-12  Havoc Pennington  <hp@redhat.com>

	* src/tools/metacity-window-demo.c (do_appwindow): make one of the
	toolbar buttons lock up the demo

	* src/window.c (meta_window_delete): move error trap to be around
	a narrower part of the function, and add part of the ping stuff,
	nothing user-visible yet

	* src/metacity-dialog.c (main): metacity-dialog executable to
	live in libexecdir and pop up dialogs for us.
