Represent python methods as static methods not static properties

[ghost]

Python.math.sin is of type PyObject.

It should be a method member sin(x:PyObject)

Stackoverflow has good docs on how to get the arguments for both builtins (using documentation scripting) and regular methods (using 'inspect')

Fixed it for built-ins (which is harder). The next step regular functions.

[dmitry-a-morozov]

fixed for non-built-ins too
