VideoPlayer: Make PlaybackManager use OwnPtr

Browse source 
VideoPlayerWidget was keeping a reference to PlaybackManager when
changing files, so the old and new managers would both send frames to
be presented at the same time, causing it to flicker back and forth
between the two videos. However, PlaybackManager no longer relies on
event bubbling to pass events to its parent. By changing it to send
events directly to an Object, it can avoid being ref counted, so that
it will get destroyed with its containing object and stop sending
events.
