Moved CullVisitor/RenderStage/RenderStageLighting across to managing lights entirely within RenderStageLighting, and changed the management of modelview matrices so that RenderLeaf now stores the absolute modelview matrix, rather than a model matrix as done previously. The later allows RenderLeaf's to do a glLoadMatrix rather than a glPushMatrix/glMultMatrix/glPopMatrix.
