Alien/Parrot adapter

This is a new version of the Alien/Parrot adapter, designed to mount an AlienFC into a Parrot MiniDrone frame.
This version requires the FC to be mounted on the bottom, so that the battery can sit in the place of the stock battery.

The battery adapter piece is meant to be printed twice and glued on to the sides of the battery compartment, in order to fit a 720mah mylipo pack.
