Also hide the full screen controls when the mouse is over them.

* We just wait a little longer in this case, like 4.5s.
* Changed the code to only send the messages when needed, before they were
  being sent every 1.5s.
* However, this is untested as of yet, as the layout changes didn't allow me
  to run the MediaPlayer on my system. Will do so in a minute on another one.
