Feature: Only reset midi foot pedal on transport stop

[Josh Wolfer]

I'm stuck in an odd spot. I keep the option to zero out midi on transport stop off in order to not have my spitfire instruments mod wheel zero out. But then if there was a pedal down, my notes sustain forever on stop and I have to manually pedal in order to get it to stop.

I'd like on option that on transport stop, the pedal is zero'd out, but everything else remains the same. 

Cheers.
