Fix issue where youtube resets speed when fullscreen (#447)

Browse Source 
* Fix issue where youtube resets speed
Track the speed of a video based on its source at time of last
ratechange. Newly initialized videos with same source automatically
will use the same speed as previous video with that source.

* Make controller button press only affect that controller
* Remove deprecated settings
* Initialize speed on Play if not yet initialized
