This also makes the Playhead ignore duplicate regions. This simplifies manifest updates in DashParser by having it add every Event tag it sees. The DASH spec doesn't specify how we should detect duplicate entries or how events are fired. So to avoid firing all the same 'timelineregionadded' events on every manifest update and getting multiple enter/exit events, we will simply remove duplicates. Closes #462 Change-Id: If5d2c42bd6958567b2ec05ba1e9af252c95cf354
