Always show embroydery bg

Also:

* New backgrounds (scanned without the hardware)
* Add `config.h` to .gitignore (we have `config_example.h`)

-// [If you haven't done so already] copy config-example.h to config.h

-// When DEBUG is true, board's MAC address is printed to serial
-// Once you copy MAC addresses of both mates, use them as YIN/YANG below.
-// You can then upload the same code to both mates (each would know to
-// scan for the other one, and not for itself).
