First version of the 5x5cm sent to fab house.

Note: Doesn't include gerbers or the rocket artwork - I need more time to add an
automated way to add that artwork to the kicad source. Also, it doesn't generate
the tracks, but the kicad autorouter is sufficient in this case.
Add rocket artwork for manual merging with gerbv.
Add default traces - this only works for trivial matrices of course.
First version of the automatic trace generation for SMD breakouts.
Make automatic breakout layout more 'regular'.
Add autoconnector and silk-screen generation for matrix boards.
Use make_silkscreen instead of reimplementing the same logic.
Finishing touches for v1.
Add improved pads (large horizontal/vertical) and rocket logo.
