- Replaced integer port counts (and input/output maximum/minimum) with ChanCount, which can count multiple types and does the reasonable thing for all comparison operators

- Removed the fader/meters from MIDI mixer strips, at least until they do something
- Made the Add Route dialog refuse to create MIDI busses, Spifftacular warning dialog and all

Changes a bit more widespread than I was hoping, but worked out really well - lots of code will continue to work fine even when multi-typed (eg instrument) IOs come around, just ignoring the types it doesn't care about.  Most all changes related to counts are little search/replace deals, logic doesn't need to change.  Hopefully SVN can handle (automatic) merging with the other SoC projects if the buffer change goes as well.

Next step: do for buffers what the last two commits did for ports.
