Fix up the response signal handlers. Use returns of 0 for 'Ok' and

2003-01-07  Glynn Foster  <glynn.foster@sun.com>

	* src/calendar.c, src/entry.c, src/fileselection.c,
	src/main.c, src/msg.c, src/progress.c, src/text.c,
	src/tree.c, src/zenity.glade, src/zenity.h: Fix up
	the response signal handlers. Use returns of 0 for
	'Ok' and 'Close', 1 for 'Cancel' and 'Escape' and
	-1 for 'Uh Oh'. Get stuff printing to stderr. Fix up
	the error handling that I thought was improved,
	although still have issues with popt callback getting
	called numerous times because of more than one instance
	of the same kind is being used in poptOption.

	* TODO: Update accordingly.
