VideoPlayer: Start fleshing out the user interface

Browse source 
This adds player widget with working play/pause controls, a seek bar
which currently only displays the current playback position, and a
button to cycle between the scaling modes.

The player uses the new PlaybackManager class to handle demuxing,
decoding, and frame presentation timing.

Currently, the volume control is non-functional.
