Add video sensing debug C_CELL and AB_CELL views

Browse source 
- Rename UV to UV_CELL, UV cannot be rendered in a non-cell format

Modify C and AB views as well to better represent in color the work being done.
If you watch the debug views with XY_CELL, AB_CELL, C_CELL, and UV_CELL you can
see how AB_CELL and C_CELL affect UV_CELL in similar color patterns.
