Closes #1384: Parse and interpret See Also section the way NumpyDoc does

The NumpyDoc extension that is developed by the Numpy folks does a lot
of extra work interpreting See Also sections. It assumes that the contents
of the See Also will always be references to other functions/classes and
it tries to deduce what is being referenced.

I've ported their implementation for See Also sections written in the
Numpy style. There is NO extra interpretation done for See Also sections
that are written using the Google style.
