- Huge cleanup of LUT stuff.

- No longer stores a sawtooth waveform twice, once with each sample negated.
- More graceful handling of truncated waveformcache files.
- Fixed tuning of patterns for non-32KHz sample rates (needs checking).
- Note: Waveform cache format changed, will automatically be rebuilt.
