Wez Furlong 712476cd28 Add support for Adafruit BLE modules
This implements some helper functions that allow sending key reports
to an SPI based Bluetooth Low Energy module, such as the Adafruit
Feather 32u4 Bluefruit LE.

There is some plumbing required in lufa.c to enable this; that
is in a follow-on commit.
