	* app/plug-in/plug-in.[ch]: added separate GMainLoops for waiting
	for extension_ack and for procedure_run's return value. The stack
	of main loops is currently unused, it will be used for temp_proc
	return values (which are currently disabled for no good reason).
	Removed the boolean "recurse" and "starting_ext" states because
	they are redundant now (we check for the presence of the dedicated
	main loops instead).

	* app/plug-in/plug-in-message.c
	* app/plug-in/plug-in-progress.c
	* app/plug-in/plug-in-run.c: changed accordingly.
