Shield pin usage list

Thanks for that list Mowcius.

I've tabulated that, looked at a stack of schematics, and generally faffed around to come up with this.

Coding badly: I've done the ones from the Arduino site as well, although most were also on Mowcius' list.

Many still have ? in their row, sometimes this is because there doesn't appear to be a public schematic, with others it's because I had to download a ZIP and haven't got around to extracting the schematic yet.

I've had enough for the moment, gone cross-eyed looking at this lot. But if it's worthwhile I can verify more over time, or maybe others can chip in or the owners of these boards can tell us exactly what pins they use.
