fix bugs with CSQC clearscene function - it now restores the view to

what was given to CSQC_UpdateView in the first place
fix bugs with getpropertyvec(VF_FOV) - it reads view.ortho_x and y
values assuming they are the original angles, so these needed to be set
correctly by the engine before invoking CSQC_UpdateView
