Good job, Phreak.

If you're looking for something else to do in the tech room, try this, it would be A-1 Supar!!!!1:
Right now the ships database displays ships based on their numerological position in the ships.tbl. So if ship entry number 27 is supposed to be a hidden one in the official

ships.tbl, and one adds a mod into, say, the 16th position, then all entries after 16 are bumped down one and the ship originally in position 26 is moved to position 27 and becomes invisible in the tech room, while ship 27 moves to position 28 and becomes visible when it shouldn't be.
If we could change this so that the choice to display a ship or not is based upon its name, rather than its position in the table, that would be a good thing, I think. It might not be too hard either, since the tech-add-ship sexp already functions on a name based system. Perhaps it might just involve a little bit of creative copying and pasting?
