Firmware upgrade for Windows

[nomis52]

We need to figure out and document how to upgrade the firmware from Windows.

The bottom link works fine on Win 7.

Although we then need to work out what interface is what and load some sensible drivers to make them useable.

@peternewman do you mean you've actually loaded f/w using the last link?

Correct, it throws an error about not being able to disconnect or something, but I only flashed the bootloader via ICSP and did everything else with DFU. I'll do something more serious later like change the device name, just to prove DFU is really working. Also given it's libusb, I think USB on Windows should just work too!
