py-furl: updated to 1.1

Furl v1.1
Fixed: Support and preserve all query strings as provided. For example, preserve
the query '&&==' of 'http://foo.com?&&==' as-is. Empty key=value \ 
pairs are
stored as ('', None) in Query.params, e.g. [('', None), ('', None)] for the
query '&'.

Changed: Don't encode equal signs ('=') in query values if the key is empty.
That is, allow and preserve queries like '?==3==' while also percent encoding
equal signs in query values with an associted key, as expected. E.g.
'?a=1%3D1'.
