[Common::GameplayEvents::GameplayInputListener]
* The DEBUG_CAMERA_TOGGLE action event has a boolean state to determine if the
  camera should be active or not
[Common::Game]
* In the main loop under Execute, all new key state is sent to the event
  router, on an Intel Core i7-4770 processor under Gentoo Linux, this takes
  approximately 150 microseconds to perform
* The F12 key should toggle the state of the mouse grabbing the window,
  however, this is not working right now, as the mouse is warped to the centre
  at the end of each update, regardless
