[WIP] Added support for the b.face keyboard (#2493)

* Added support for the b.face keyboard

This commit adds support for the 60% keyboard from winkeyless, the
b.face. The basic keyboard layout as well as the RGB backlighting
works as expected; the per-key LEDs can be turned on or off but not
yet dimmed. A default 60% US-layout is included.

* Added link to the bface in the ps2avrGB README

+ps2avrGB keyboard firmware
+==========================
+
+This is a port of the QMK firmware for boards that are based on the
+ps2avrGB firmware, like the [ps2avrGB
+keyboard](https://www.keyclack.com/product/gb-ps2avrgb/) or the ones sold
+by [Winkeyless](http://winkeyless.kr/product/ps2avrgb-parts/).
+
+Note that this is a complete replacement for the firmware, so you won't be
+using Bootmapper Client to change any keyboard settings, since not all the
+USB report options are supported.
+
+## Supported Boards
+
+Only the [B.mini X2](http://winkeyless.kr/product/b-mini-x2-pcb/) has been
+tested so far (since it's the only one I own). But other boards that use
+the ps2avrGB firmware should work as well.
+
+## Installing
+
+First, install the requirements. These commands are for OSX, but all you
+need is the AVR toolchain and `bootloadHID` for flashing:
+
+```
+$ brew cask install crosspack-avr
+$ brew install --HEAD https://raw.githubusercontent.com/robertgzr/homebrew-tap/master/bootloadhid.rb
+```
+
+In order to use the `./program` script, which can reboot the board into
+the bootloader, you'll need Python 2 with PyUSB installed:
+
+```
+$ pip install pyusb
+```
+
+Then, with the keyboard plugged in, simply run this command from the
+`qmk_firmware` directory:
+
+```
+$ make ps2avrGB-program
+```
+
+If you prefer, you can just build it and flash the firmware directly with
+`bootloadHID` if you boot the board while holding down `L_Ctrl` to keep it
+in the bootloader:
+
+```
+$ make ps2avrGB
+$ bootloadHID -r ps2avrGB_default.hex
+```
+
+## Troubleshooting
+
+From my experience, it's really hard to brick these boards. But these
+tricks have been useful when it got stuck in a weird scenario.
+
+1. Try plugging the board in while pressing `L_Ctrl`. This will force it
+   to boot only the bootloader without loading the firmware. Once this is
+   done, just reflash the board with the original firmware.
+2. Sometimes USB hubs can act weird, so try connecting the board directly
+   to your computer or plugging/unplugging the USB hub.
