A lot of changes improving Trident performance

Stairs are now detail brushes. Small things in doorways are too.

Placed some hints. Maybe I'm not as good as I expected, but hint on stairs near jump pad and mega improves performance near one-way portal.

Extended caulk faces of some brushes, added caulk brushes, removed some invisible brushes. More caulk faces.

Changed outer wall near large armor, so it will not generate wierd vis portals. Replaced to caulk part of outer wall hidden behind rock on mega side.
