Stream:CC14() added, Stream:CC() outputs normalized values, got rid of Stream:ccscale()

* Stream:CC14() allows reading 14-bit CCs (split over two 7-bit MIDI messages).
  It's actually capable to handle regular 7-bit controllers just fine.
  The question is whether we still need a distinction between Stream:CC() and Stream:CC14().
  Stream:CC14() has a slight overhead, but only when actually receiving MIDI messages.
* Stream:CC14() and Stream:CC() output values normalized to [-1,+1] now.
  We actually never made use of raw CC values and the scaling can be done only once whenever
  a matching MIDI message is received, so the runtime overhead is irrelevant.
* This means we could also get rid of Stream:ccscale() now.
  Just use Stream:scale() from nowon.
* Use Stream:scan() now whenever relying on previous values.
  That way, you can often avoid having to keep an accumulator variable in the closure.
