Documentation: Corrected Hoodloader2 description.

Documentation: Add Adafruit's Atmega32u4 breakout board.

Added include guards for DMBS build modules (thanks to Nico Hood).

Added HID_KEYBOARD_SC_RESERVED (thanks to Nico Hood).

Added include guard for dmbs modules. Fix https://github.com/abcminiuser/dmbs/issues/28 already included.

Fixed bootloaders not disabling global interrupts during erase and write operations (thanks to Zoltan).

Fixed DeviceUsesOUTPipe flag not being set correctly in the HID host class driver (thanks to Wolfgang Schnerring).

Fix invalid value in HID_DESCRIPTOR_KEYBOARD() (thanks to Eric Tang).

This will prevent future occurrences of jackhumbert/qmk_firmware#312.

Fix incorrect serialization in USB_SetHIDReportItemInfo() function (thanks to e-chip).

Bits applying loop worked incorrect on large reports. Seems to me like a
copy/paste problem from USB_GetHIDReportItemInfo().

Update functions used to write to EEPROM (thanks to Eric Tang).

Replace LUFA build system with its successor, DMBS, for easier maintenance.
