Patches now drawing correctly

Need to integrate into drawVBO function and apply proper texture. There
are still holes in the map. Filled by MD3 models, or we're missing some
verts
Patch textures are now correct

This is a dirty hack. The rendering for BSPs really needs to be built
into the BSP class and simply called from j7*
Replaced some datatypes with GLM

Removed SFML vector types from BSP files.
Simplified BSPVertex operator overloads
Add user definable tessellation level
Remainder of non-control sfml vector datatypes changed to GLM
Some cleanups

Moved unused code to another file.
Eliminated a control bool.
Straightened up some whitespace.
Fixed a vertex color bug. More cleanups

There seems to be a weird seam in the patches when lighting is disabled.
Is it because I haven't normalized the patches?
