Latest WIP update

Peppy integration mostly done.
- ALSA level FIFO pipes used (no need for player-specific FIFO's or Loopback)

TODO:
- Deb packages for PeppyALSA, PeppyMeter and PeppySpectrum
- DSD native option ?
- Config Screens for peppy config.txt, meters/spectrum.txt ?

Not working: PeppySpectrum
