Kitspace fixups

[kasbah]

Hello, I made some small adjustments to make this work with Kitspace.

• Used the right path in kitspace.yaml
• Re-plotted the gerbers using the Oshpark CAM job (due to https://github.com/tracespace/tracespace/issues/73) and removed the rar file to make sure people know which of the gerbers are the up-to date ones.

Lastly I replaced the pcb_design folder with the sangaboard folder since you mentioned that that would make sense. I can undo that last thing as it's kind of unrelated, let me know.

Preview is up: http://add-openflexture.preview.kitspace.org/boards/github.com/kitspace-forks/openflexure_nano_motor_controller/ (yes, I know it's spelled flexure not flexture).

I've submitted a request - hopefully that's us :) I should probably fix the readme and update the website though...
