Verify headless - autoplay file

[cswales]

Verify that the raspberry pi has enough umf to run a full sculpture by recording a set of patterns on the full sculpture and attempting to play them back on the raspberry pi.

Check resource usage as the pi is running, since this is the only thing we can do without actually having the sculpture to work with.

Status: service works, but starting the unhappy directory. Want to move cwd to /home/pi/Chromatik, then can put the autoplay file there
