Very tiny patch

-Changed the text on the "Communications" Auxilliary power unit as it's misleading, it enables the computers not the communications. The communications, external communications to HQ that is, can't be restored. Which may have led to confusion about the communications option in the save terminal. Lord that took a year to fix that mistake.

-Change a thing that can only be done once per sesson to a thing that can be done more than once per session.

-And ditto for another.

-Small lighting bugfix.
