Added file-exists.glade.

2001-08-01  Christopher James Lahey  <clahey@ximian.com>

	* gui/contact-editor/Makefile.am: Added file-exists.glade.

	* gui/contact-editor/e-contact-save-as.c (file_exists),
	gui/contact-editor/file-exists.glade: Added a dialog to ask the
	user whether to replace an already existing file.  Mostly from a
	patch by Jos Dehaes.  Fixes Ximian bug #2231.
