Implement MediaSessionManager to keep track of all MediaSessions

• Status: RESOLVED FIXED

[Matt Rajca]

As described in the Media Session spec, MediaPlayPause events need to be handled by each Media Session, and we need a MediaSessionManager to keep track of them.

Normally it’s not good to use remove/find. I’d suggest using a HashSet or ListHashSet for this collection instead of a vector.

Settled on HashSet since we don't care about the ordering of MediaSessions. Thanks!

Is there any reason to not make this private?

I have other uncommitted code here locally that requires it to be public, but that is probably going to get refactored anyway. I'll remove the accessor for now.
