Fix quad hex ufc geometry

Added some changes to ufc_geometry.h so that everything is in the agreement with FIAT's hexahedron and quadrilateral reference element.

• Changed local reference cell coordinates

• Changed quad edge vertices

• Changed quad facet vertices

• Changed hex facet vertices

• Changed hex facet edge vertices

• Added quad_reference_facet_jacobian

• Added hex_reference_facet_jacobian

• Added quad_facet_midpoint

• Added hex_facet_midpoint

• Fixed hex_facet_edge_vertices

• Fixed hex_ref_edge_vectors

• Fixed quad_ref_facet_normals

• Added facet_orientations, but left it commented out because not sure about the correctness
