doesn't work with argument type hinting

[EdsterG]

Here's an example that breaks auto generated docstring templates:

def foo(bar: str):
    pass

the result is:

    """[summary]

    [description]
    :param bar: str: [description]
    :type bar: str: [type]
    """

it should at least parse the name correctly:

    """[summary]

    [description]
    :param bar: [description]
    :type bar: [type]
    """

and ideally it would auto file the type:

    """[summary]

    [description]
    :param bar: [description]
    :type bar: str
    """
