Merge pull request #1547 from ClassiCube/PSPClipFix

PSP clipping fixes part 1

Undo temp debug changes

PSP: write a few GPU commands directly

PSP: Avoid setting base command for clipped polygons

PSP: Don't break run if quad is culled by visible frustum

PSP: Refactor plane clipping function to do the loop there

PSP: Don't test near plane and let GPU handle that instead

Majorly cuts down on number of quads that go through slower clipping path

PSP: Cleanup assembly

PSP: Most chunks skip clipping path

PSP: also clip against Z planes

PSP: Partially fix sky

PSP: Split up checking assembly

PSP: Fix quad needs clipping function
