Update For Twitter's PIN Changes

[GoogleCodeExporter]

This library could use a small update to make it work nicely with today's
changes to how Twitter uses OAuth.  Here's how I got around the change:

  def getAccessToken(self, pin, url=ACCESS_TOKEN_URL):
      token = self._FetchUrl(url, parameters={'oauth_verifier': pin},
no_cache=True)
      return oauth.OAuthToken.from_string(token)

...where "pin" is the 6-digit PIN that the user gets from Twitter after
having authenticated something.
