Add bits that are done so far

This includes:
* Controller (runs and responds to calls placed on the screen, parameter editing and switches work)
* Null Drive (simulates motion so the controller can run, no actual movement yet)
* Call Buttons (lights can be toggled with right-click, no communication yet)
