Filter WMO decorative geometry from collision, fix tram portal trigger IDs

Browse source 
Parse MOPY per-triangle flags in WMO groups and exclude detail/decorative
triangles (flag 0x04) from collision detection. This prevents invisible
walls from objects like gears and railings in WMO interiors.

Add WotLK area trigger IDs 2173/2175 to extended-range tram triggers.
