Import libretro-picodrive-20150203 as emulators/libretro-picodrive.

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.

PicoDrive is a Sega 8/16 bit video game system emulator.
