superclass for both EContactEditor and EContactListEditor. A start toward

2004-03-24  Chris Toshok  <toshok@ximian.com>

	* gui/contact-editor/eab-editor.[ch]: superclass for both
	EContactEditor and EContactListEditor.  A start toward simplifying
	the interface to both of them, and a place to abstract code.

	* gui/contact-editor/Makefile.am (libecontacteditor_la_SOURCES):
	add eab-editor.[ch]
