Equivalence of smoothness with the basic definition for functions between vector spaces

• contMDiff_iff_contDiff: for functions between vector spaces, manifold-smoothness is equivalent to usual smoothness.
• ContinuousLinearMap.contMDiff: continuous linear maps between normed spaces are smooth
• smooth_smul: multiplication by scalars is a smooth operation
