Missile launcher is nice, now I can get to building that MechWarrior-inspired Catapult ship that's been floating around in my head.

And the thruster is also much welcome.
Import ship GUI is awesome, now there just just needs to be an improvement of some kind to the spawn normal ship/enemy message box, as it seems kinda dated compared to the shiny GUI.

Actually, it's fine as-is, it would just be nice if there was a button that brought up a list of the numbers associated with each ship, so it was less guesswork.
