S-Core firmware 0.96 - fix unintended trigger trap when full auto and decelerateBoltToSwitch() (etc.)

This fixes a bug in which

• firing full auto
• releasing the trigger momentarily overlapping with a trigger polling event, thus initiating drivetrain deceleration in preparation for firing to end
• pulling the trigger again during the deceleration

-would incorrectly be trapped by the disconnector and do nothing until the trigger was reset, as if it were a continuing trigger-down state after a burst or semi shot has been fired. This little death slot could be found when thrashing a blaster with "stop and go" type input on full auto. Plenty of players may make inputs like this, including me, under pressure.
