It took ages for me to edit all of the ship thumbnails, but the deed is finally done. Around 50 ships sprites were replaced due to an artist's request, and 15 new ships were added. I'm approximately 70% way through all of the ships, so that's a good start. The wormhole has also been fixed, so it should be possible to move in between the Star Wars and the vanilla galaxies.

Edit: Ok, I just re-uploaded it. It turns out I hadn't updated the map.txt file in the earlier release, so the wormhole won't work in that one.
