Refactored pavara.geom

Did a little house cleaning before tackling more procedural mesh
"types." Included a bit of optimization -- blocks with a height of 0
will now render 4 tris instead of 12, for example.

Fixed an issue where rotated dome members of composite objects had
faulty collision shapes.

Also a lot of white space got cleaned up DAMNIT CROC
Added Wedge objects.

Thanks @jonathanvoss for teaching my dumb ass about vector operations!
Model updates, fixes for hector
