fixed view location bugs in csqc; it was reading the player entity's render.origin field, which was broken...  removed the origin and angles fields from entity_render_t and eliminated all references
renamed CL_BoundingBoxForEntity to CL_UpdateRenderEntity and made it update the entity_render_t inversematrix and scale according to the matrix, and also calls R_LerpAnimation, this reduced code elsewhere
