Changes includes:

- Improved runtime control system
- 3 New filter panning, compressor/limiter and a noise gate
  - The compressor/limiter and the noise gate are not yet finished
  - The panning filter does combined mixing and channel routing and
    can be used to down-mix from stereo to mono (for example)
- Improvements to volume and channel
  - volume now has a very good soft clipping using sin()
  - channel can handle generic routing of audio data
- Conversion of all filters to handle floating point data
- Cleanup of message printing
- Fix for the sig 11 bug reported by Denes
