	* pcs/cal-backend.c: Move some non-file-backend-specific stuff
	from cal-backend-file here so it can be shared with other
	backends.
	(CalBackendPrivate): add this, containing the categories hashes
	and the (formerly public) clients list.
	(cal_backend_init, cal_backend_finalize): Handle backend->priv.
	(cal_destroy_cb): Simplify this (and redo it as a weak notify
	func)
	(cal_backend_add_cal): Keep a weak ref on the cal rather than
	connecting to its "destroy" signal. Call notify_categories_changed
	to let the new cal know about them.
	(get_object): Default implementation of cal_backend_get_object.
	that calls cal_component_get_as_string on the return value of
	cal_backend_get_object_component.
	(cal_backend_notify_mode, cal_backend_notify_update,
	cal_backend_notify_remove, cal_backend_notify_error): Notify each
	Cal about something.
	(cal_backend_ref_categories, cal_backend_unref_categories):
	Maintain a list of categories that are used by components in the
	backend, and trigger categories_changed notifications as needed.

	* pcs/cal-backend-file.c: Remove stuff that was moved to
	CalBackend (notify funcs, category handling, get_object
	implementation)
