disconnect source/target_editable signal ids.

2004-06-30  Chris Toshok  <toshok@ximian.com>

	* gui/contact-editor/e-contact-editor.c
	(e_contact_editor_dispose): disconnect source/target_editable
	signal ids.
	(e_contact_editor_set_property): disconnect/connect editable
	signals.
	(writable_changed): new function - we need this since writable
	status is generally communicated asynchronously with the async
	interface.

	* gui/contact-editor/e-contact-editor.h (struct _EContactEditor):
	add source/target_editable_id slots.
