A little cleanup for PIXO Pixel
A little cleanup for PIXO Pixel

Touch up the code here and there for human consumption ;-)

And this should be ready to go to code PIXO Pixel:
- 16x16 configuration, non-zigzag
- MAX_MILLIAMPS added, set to 3A
- Second set of data/clock pins set to PIXO defaults

This *will* try to connect to wifi; you'll need to fill in your
SSID/password for that (and OPC support) to work.
