Change to VR Controller Enable/Disable

[Ich Dien]

The toggle control for disabling the left and right hand controller works as expected, however if this function is bound to the hand controller being disabled, then it's not possible to re-enable the same hand controller using this binding; it has to be bound to a different device or it's only good to disable the hand controller once and afterwards there's no way to get the controller back.  

I can understand why the sim isn't listening for all button presses on disabled controllers, but it stands to reason it should be possible to at least disable/enable a hand controller using only one button on said hand controller. Currently the UX is awkward in my opinion. 

Thanks,
