World: add prop tint and fog override

- World tint now also colours prop materials (models/props*) with their own
  colour, covering static props and prop_physics while leaving NPC, player and
  weapon materials untouched.
- New Fog card: fog_override colour/start/end via ClientCmd, optional skybox
  fog, and a Remove fog mode. Restores the map fog (fog_override 0) when
  disabled and re-applies after level changes.
- Config sections [worldtint] prop/colour keys and [fog].
