Send kfw 'obtain ticket' messages to main frame

Send kfw 'obtain ticket' messages to main frame

Previous versions of kfw would attempt to send 'obtain tickets' messages
directly to the 'view' window by sending to the first child of the main
frame.  But with the ribbon UI, the ribbon toolbar is now the first child,
so that method no longer works.  Instead we now send the message to the
main frame and the main frame forwards to the active view.
