/** Handles the conversion from some input to a GameAction and its distribution
* to the currently active menu.
* It also handles whether the game is currently sensing input. It does so by
* suppressing the distribution of the input as a GameAction. Instead the
* input is stored in 'm_sensed_input' and GA_SENSE_COMPLETE is distributed. If
* however the input in question has resolved to GA_LEAVE this is treated as
* an attempt of the user to cancel the sensing. In that case GA_SENSE_CANCEL
* is distributed.
*
* Note: It is the obligation of the called menu to switch of the sense mode.
