CHIMneys (Corrected UVs and Added LODs)

[BethOfDeath]

ex_common_chimney_tall:

• Reunwrapped UVs to reduce distortion.
• Added LOD1: 2 drawcalls (reduced by 1), 142 tris (40% reduced)
• Added LOD2: 1 drawcall, 74 tris (69% reduced)
• Vanilla: 17244 bytes, previous MOP 17530; now 26511. (+54% vs vanilla, +51% vs previous MOP)

ex_c_chimney_tall_02

• Recombined and further split collision mesh
• Chopped up new ex_common_chimney_tall and shifted to new location.
• Vanilla: 14644 bytes, previous MOP 14302; now 21201. (+45% vs vanilla, +48% vs previous MOP)

ex_nord_chimney_01:

• Simplified collision mesh from 36 tris to 12.
• Corrected self-intersection in capstone. Adds 16 tris, I think.
• Reunwrapped capstone to reduce seams. There are still some around the corners, but they look less noticable to me.
• Added LODs to reduce from 4 drawcalls to 2, then 1 with simplified geometry (LOD0 104 verts 130 tris, LOD2 30 verts 52 tris)
• Vanilla: 10697 bytes; new: 16018. (+50%)
