This adds support for the Blinkinlabs BlinkyTape controller, a USB-powered digital LED strip controller. Devices are detected automatically by scanning for their VID/PID, and connected to using serial. This code was tested in Windows. Commit squashed and amended for code style and to fix Linux build by Adam Honse <calcprogrammer1@gmail.com>
