map 2, added sewer light option. m3 added lower exit light option. map 4 fixed bad item spawn location.map 5 minor script name changes, map6 fixed rescue closet spawn location. All scripts checked and fixed for double spawn script error. Scripts improved by adding more accurate messages for checking for errors.

Modified path options on map 1. Added vesus ladders and fixes on map 4, and fixed (as much as possible) nav blocking to discourage bots going through the alarmed door when garage doors are open. Added light to campan's sewer path on map 5. Made some sewer sections of map 5 not slime, so it is easier to get on one ladder. Blocked tunnel in map 6 to prevent vesus infected from spawning in a location where they can get stuck.
