implement replay analysis into spectating

[Sheppsu]

Implements the replay analysis overlay into both solo and multiplayer spectating. For multiplayer spectating, the settings container is added on the left side under the leaderboard. For solo spectating it works the same as watching a replay.

Look of the settings container during multiplayer spectating:

Not sure if parsing new frames during each update instead of all at the beginning means the logic in addEntries should be changed to async now, though I haven't had any performance problems running it.

Also now that it's not all parsed at once, would it be better to limit how far ahead it adds entries for? The purpose being to lessen the initial strain for larger replays being viewed in solo.

Please don't do that until it's necessary.

Didn't plan to; that's why I'm commenting about it.
