Check source book writeability directly instead of relying on stored

2004-07-16  Hans Petter Jansson  <hpj@ximian.com>

	* gui/contact-editor/e-contact-editor.c (contact_added_cb)
	(save_contact)
	(app_delete_event_cb): Check source book writeability directly instead
	of relying on stored state.
	(e_contact_editor_init): Don't init source_editable.
	(e_contact_editor_dispose): We don't listen for source writeability
	anymore.
	(writable_changed): Source writeability doesn't affect widget
	status; remove code to check for it.
	(e_contact_editor_set_property): Do nothing if book being set is
	the same as currently set book; previously we would end up
	unreffing then reffing it. Don't watch for source writeability, but
	do so for target; fixes a warning. Only call sensitize_all() if
	writeability on target changed.

	* gui/contact-editor/e-contact-editor.h (EContactEditor): We don't
	need the source_editable and source_editable_id vars anymore.
