Bug fixes

Changes:
1) Changes the Mortician alternative title to Coroner.
2) Gives the Chief Engineer a pair of superior welding goggles.
3) Fixes the customs windows not coloring.
4) The labcoat can now hold more items.
5) Oxygen first-aid kits now have in-hand icons.
6) The AI can now add security notes.
7) Fixes the snow/gifts on the map.
8) Speaking over the radio when hurt now produces a feedback message.
9) Other map fixes.
10) Drones can now decompile lights.
11) Adds the forensic scanner/autopsy scanner to R&D, so it can be built in case the one that's on the map is lost for whatever reason.

Note: For some reason, it did not let me mapmerge, even after re-doing the changes twice. This may be due to the snow changes? Either way, if this causes any conflicts just overwrite my map changes as they're all very minor, after which I'll just re-do them.
