- Help window text cleaned and made more consistent between game and editor - Added help entry for "-clipmap" - Log text for using CON, DEF, and RTS files has been made consistent - All instances of '%s' have been replaced with \"%s\" because ' is a valid filename character. (At least on Windows.) git-svn-id: https://svn.eduke32.com/eduke32@2538 1a8010ca-5511-0410-912e-c29ae57300e0
