* Timeline didn't listen to file read notifier, so the pointcache frames indicator didn't get updated. * Also added listens to particle & modifier (cloth, sb & smoke) notifiers as changes that cleared a pointcache weren't shown directly in the timeline either. * The timeline display was also always one frame behind the actual state, since the notifiers are handled before the actual dynamics are calculated. ** This is now fixed too, by creating the actual drawn data always at drawtime.
