Import libretro-gambatte-20150204 as emulators/libretro-gambatte.

Libretro is a simple but powerful development interface that allows for the
easy creation of emulators, games and multimedia applications that can plug
straight into any libretro-compatible frontend. This development interface is
open to others so that they can run these pluggable emulator and game cores
also in their own programs or devices.

Gambatte is a Nintendo Game Boy/Game Boy Color video game system emulator.
