Stephen Evanchik's patch to Update scheduled transaction dialog.

        * src/gnome/dialog-sx-from-trans.c:
          - Removed per-button callbacks in favor of a 
            dialog response callback
	  - Changed per-button callback functions to 
	    simple 'action' functions that are called
	    in the response handler.
          - Migrated away from gtk_signal_connect
          - Removed references to GNOME 1.x dialog
          - C Style changes: 'open curly brace on same line'
          - Moved 'public' function gnc_sx_create_from_trans
	    to the bottom of the file
