Update and rename 7.15.14.96ppq.build to 7.15.14.build

Improves MIDI file listStart, this build checks for the next event at the full 96ppq, but only sends clock at the 24ppqn (every 4th pass int the code).  also some possible improved looping timing.  I had dropped the checking of the tick function, but adding it back in seems to be better timing for looping.
