Lipsync Curves and Gradients

1. Modified LipSync Effect to use Rasterize and provide better view of channel states at the Phoneme level
2. Added ability to set dimming curves and gradients at the phomeme level.  These will override or offset those set in the map.
3. Added "Explode" capability such that a phoneme can be converted to it's sub group element states for better modification by the end user.
