Add function docstrings

[hugovk]

Some of the functions in vanity.py have empty docstrings, for example:

def normalize(name):
    """
    """
    http = HTTPSConnection(PYPI_HOST)
    http.request('HEAD', '/pypi/%s/' % name)
    r = http.getresponse()
    if r.status not in (200, 301):
        raise ValueError(r.reason)
    return r.getheader('location', name).split('/')[-1]

It would be great to fill these in.

Hello @masterp4dev,

Sorry for the PR, I'd already started working on this. Please feel free to submit your own PR, it is entirely possible your changes might be more suited to @hugovk 's needs. :)
