Replay editor

The replay editor is still a buggy mess. Keyframes were finally added, but it's almost impossible to use the feature because if you rewind or stay in the editor too long, it starts stuttering or just freezes altogether. On top of that issue, which has been persistent since launch, now when you try to edit a clip with other players in it, half the time they rubberband in the replay, and you have to either try and redo it or completely give up.
