Hemisphere: Logarhythm Branch 0.9

• TB-3PO: CV applied to the 'density' parameter is now an offset from the value set by the encoder, rather than superseding it. Setting density with the encoder works as before, except it can now be done while CV is applied (and its value is shown momentarily with a 'knob' icon in this case.)
  CV +-2.5v will offset approximately +-7 density values from the encoder-set position.
  The pre-1.9 CV behavior can be emulated by setting the encoder value to -7 and applying 0-5v, giving the full range under positive cv control.
  (Thanks to Muffwiggler user qiemem for the suggestion!)

• Shuffle: OutputB was unused in the stock firmware, so now it outputs Triplets. It detects the clock tempo and emits 3 triplet pulses evenly distributed across 4 clocks, starting at the first input clock. Reset is shared with the shuffle odd/even output. No input parameters affect the triplets-- it's just a bonus output that can be fiddly to patch normally and pairs well with swing. No dubstep was accidentally made in testing this feature.
