I created this file to store some commonly used enumeration to string

	* gui/itip-utils.[ch]: I created this file to store some commonly used enumeration to
	string mappings and functions.
	* gui/Makefile.am: this was changed to reflect the addition of the above file.
	* gui/e-itip-control.c: added code to take action on a REPLY message.
	* gui/e-meeting-edit.c: bug fixes.
