Finish re-working the other plugin's engines...
Merge note, CC and pitchbend events into a single list that is sorted
without regard to type...

This work is mostly for sample-accurate automation, but also can
improve efficiency and scalability...
Add -Wall to the standalone project debugger...
Set the values manually instead of using memset...

(because it's relatively convenient to do so now, plus I don't
trust memset with real-time stuff anyways...)
