Added callback_url parameter to Twython to set the URL the remote

Browse source 
site will use to return the request token.

Supports both OAuth 1.0 and 1.0a methods of setting the oauth_callback
parameter. For OAuth 1.0a support, a patched version of python-oauth2
is currently required (see
https://github.com/simplegeo/python-oauth2/pull/43).

Availability of OAuth 1.0a support in python-oauth2 is autodetected
and a suitable warning is given if the remote site requires it but
python-oauth2 doesn't support it.
