Added pulldown on the B port ~CTS ftdi line. Closes #10

With this line pulled down we can use minicom even when hardware flow
control is enabled. If this pin is not pulled low and hardware flow
control is used, no data is ever sent out by the FTDI chip. This can
easily happen because minicom has hardware flow control enabled by
default.

I decided to only add the CTS line pulldown to keep the placements under
control.

Use normally closed jumpers. And fix VCCIO2 bypass. Closes #11

These jumpers connect two nets without impacting the schematic net
lists. This is a safer solution and easier to read than having to
remember where the net jumpers have to go and not miss a side path.
These jumpers use a hack of KiCAD where the DRC ignores lines on the
copper layer in footprints. The two pads of the jumper are shorted
within the footprint but they are not from the perspective of the DRC.
While I was already at it I have also replaced / separator with |
separator for multifunction nets. Unfortunately KiCAD reserves the /
separator for its multisheet net naming. This patch should fix the
bypass of the VCCIO0 jumper that was a mistake in the previous versions
of the board.

Initial commit of icebreaker V1.0a hardware.

Work in Progress.
