[input] Ensure button id is never 0

Browse source 
IN_ButtonAction treats id 0 as not pressed in its internal processing,
and the previous input implementation treated 0 as "no key", so this is
both the simplest and most correct fix.

Fixes mouse left button not working every second time the game is run
(due to keyboard and mouse bindings swapping places in the config file
(separate issue, if it really is one)).
