Vas make big gun go boom!

I fixed a quick typo left behind from from when the Subbing of individual ships was added. 

I've added Firing of the BFG, in which the user will select one of the stars that have been seized by the station, and then one of the bodies orbiting that star, type in a reason and hit "Fire".

I made the PopulateBodiesForStar() non specific to the BFG so tht it can be reused in the implementation of Evict Mining Platform, Rename Planet and Rename Asteroid.
