absolute and relative norm functions for number field elements

[sagetrac-MvanBeek]

Although number_field_element.pyx has a norm method, it does not have absolute_norm() and relative_norm(). This would be a useful shorthand to have.

I've applied the patch and did all the tests for rings (all passed). I've also done some computation of my own. I've looked at the code and it looks fine. I've built the documentation and it looks fine.
