- Categorized invisibility stuff into #defines. If any errors appear - let me know.

- Hopefully addressed the concerns about the ultra-darkness. Night vision, mesons, thermals and material scanners now make you see through darkness. (Lighting code does not affect you)
- Ghosts get a "toggle darkness" verb, which changes their see_invisibility. When the toggle is enabled, ghosts cannot see other ghosts. This is due to invisibility.
