Add some utilities to:

	set the "activate" signal for a widget to call a routine to
	activate the "OK" button for a dialog box;

	set the "key_press_event" signal for a top-level dialog window
	to call a routine to activate the "Cancel" button for a dialog
	box if the key being pressed is the <Esc> key;

to make it easier to drive dialog boxes entirely from the keyboard.

Make the "Find Frame" and "Go To Frame" dialog boxes use those
utilities.
