pcw2hid: Add bootloader

Forked from LUFA DFU bootloader.

Flash fuses: lfuse 0xEF, hfuse 0xD8 (enable BOOTRST) efuse 0xF7

This means the boot always goes to the bootloader first. The bootloader
wait for a while to see if there is any activity on the keyboard pins,
in that case, it jumps to the main app. Otherwise, the device enters DFU
mode and can be upgraded with a newer firmware using dfu-programmer or
Atmel FLIP.
