methods but not a weighted_degree function, often used in certain branches

Comment:
I propose an alternative patch. It implements the weighted degree for all
MPolynomial, not just Singular ones. It is also faster than the original
patch. I think that, in general, it is better to use a polynomial ring
with weighted degree if one is really interested so I have added a hint in
the documentation.
