* added Envelope Generator 2 and 3 (filter cutoff EG and pitch EG) for
  accurate .gig playback
* fixed accuracy of pitch calculation
* changed filter cutoff range to 100Hz..10kHz with exponential curve, this
  value range can also be adjusted on compile time by setting
  FILTER_CUTOFF_MIN and FILTER_CUTOFF_MAX in src/voice.h to desired
  frequencies
* src/lfo.h: lfo is now generalized to a C++ template, which will be useful
  especially when we implement further engines
