	Make dialogs that Metacity shows follow focus-stealing-prevention
	conventions. (fixes one issue in #149028; see comments 47-54)

	* src/delete.c (delete_ping_reply_func,
	delete_ping_timeout_func): Make callback functions take a
	timestamp arg, (delete_ping_timeout_func): pass the timestamp to
	metacity-dialog

	* src/display.c (meta_display_ping_timeout): add a timestamp to
	the call to the ping_timeout_func, (meta_display_ping_window,
	process_pong_message): add a timestamp to the call to the
	ping_reply_func

	* src/display.h (MetaWindowPingFunc typedef): add a timestamp to
	this function typedef

	* src/keybindings.c (error_on_command): require a timestamp and
	pass the timestamp on to metacity-dialog, (handle_run_command):
	pass a timestamp to error_on_command

	* src/metacity-dialog.c (copy_of_gdk_x11_window_set_user_time):
	new function (temporary; only for use while using gtk+-2.4),
	(kill_window_question, warn_about_no_sm_support,
	error_about_command): make these functions take a timestamp and
	call copy_of_gdk_x11_window_set_user_time, (main): require the
	first two args to the program to be "--timestamp <timestamp>"

	* src/session.c (warn_about_lame_clients_and_finish_inter): pass a
	timestamp of 0 to metacity-dialog to prevent focus (it's a popup
	not generated by and kind of user request).
