Remove Raptor-M from the ship tree

To better match the progression in the other two factions, I propose that the Raptor-M be removed from the ship tree. It also would correspond to the other ships removed from the other factions, and would open up the tree a little more.

 

Still think this should be a thing.
There’s three low-level engineers back to back to back in Feds, and that’s kinda odd.
