Small changes to the media player (#1572)

* Resolving some issues with media playback.

* Changing ViewVideoFragment so that it fully handles autohiding the
  media controller, allowing consistency between it and the toolbar

* Fixed an issue where the toolbar and description were not fading in

* Do not hide the toolbar/media player if the video is loading or paused

* Created "ExposedPlayPausedVideoView" to allow hooking play/pause

* Fix back button when viewing videos

* Back button did not work if video controls were visible.

* Tweak audio player

* Always show the controls when audio begins playing

* Do not auto-hide the controls if the player is playing audio

* Address PR comments

* Use overloaded constructor
* Remove m prefix

* Fix subtle media player issues

* Fix audio player incorrectly auto-hiding after hiding/showing toolbar

* Only subscribe touch listener once content is ready
  - Prevents top toolbar visibility from getting out of phase with audio player visibility if hidden during load
