Improved PCB

So this is my latest version of the PCB for this project:

I noticed, that the only connections that I actually need, are the ground and power pins. So I'm not going to rely on the alternating pin holes providing good connection for those, but instead use two jumpers. All the other pins are basically just for mechanical mounting, they are not even connected. I also added some pads for SMD capacitors, in case they were preferred over the through-hole one, and moved the power-in pins.

Unfortunately, I have no way to provide access to the I²C pins -- they clash with the power and ground rails for the servo plugs. They will need to be accessed from the other side.
