EFT cfg import is broken

[blitzmann]

Two issues here:

• If the shipname isn't found, simply returns. The method that calls it is expecting a list of fits, and so it crashes.
• Tried to import cfg files from the EFT directory (which is Downloads/EFT 2.25.2/Setups) and it seems that the shipname passed is the path leading up to the first point (Downloads/EFT2). Probably a string split issue somewhere. I did not notice this when developing the new progress dialogs, but then I had those cfg files saved elsewhere.
