fixed issue #1553

[MohamedLebda]

Added mouse event so that when the mouse stops it hides the controls.

thank you! @MohamedLebda
Youtube's default for that is longer ~ 3 seconds

BTW, shouldn't we only add eventListeners when an option is activated?

Changed the code, Now the event listeners will only work when choosing when paused option.

Hi @MohamedLebda, it works when we make the setting (Storage changed) but not afterwards.
Not sure why #1331 @JuniorGenius put the eventlisteners in the init.js in the first place. The whole feature could stay one function no matter how many options(?)
