Change in handling overlapping button presses (fixes issue #824) (#907)

Browse Source 
* Modifications to input handling to prevent held inputs from being
overridden by an alternate input mapped to the same button.
i.e. R-Type holding fire to charge special shot will not be
disrupted if a secondary fire button is pressed, autofire
or not.

* Prevent held inputs from being disrupted by alternate inputs.

i.e. in R-Type, if holding the fire button to charge a special shot,
tapping an alternately assigned fire button will not cause the charge
to stop.
