LibVideo: Rewrite the video frame present function to be more readable

Browse source 
The PlaybackManager::update_presented_frame function was getting out of
hand and adding seeking was making it illegible. This rewrites it to be
(hopefully) quite a bit more readable, and adds a few comments to help
future readers of the code.

In addition, some helpful debugging prints were added that should help
debug any future issues with the player.
