Major update

Added color marking if interacted voxels ( works only for melting
voxels, not just setting them to 0 ) - + 3-5 ms.
Added relevant shanges to shaders.
Now input is the one to manage model. Added rotation and reset for model
- 'R' and 'C' respect.
SetVoxels now uses UITN8 as param, not Color*.

By design Tool should carry it's own shader - it's now done for
KinectTool.
