Fixed string formatting for Python 2.6

Breaking: token_transport parameter of Client.__init__ no longer accepts strings (which was weird to begin with). It only accepts callables. transport_headers and transport_query have been made public (well, the underscore prefix has been removed) in light of this.

Breaking: scope is now expected to be formatted how the provider expects it. scope_delim has been removed from auth_uri in order to simplify it. This means that your providers’ scope should be set accordingly: i.e. Facebook may be ‘foo,bar’ while Google would be ‘foo bar’.

Breaking: removed redirect_uri from Client.__init__ (didn’t make sense to be there. This has been added to auth_uri and request_token.

Deprecation: sanction.client.Client has been deprecated in favor of sanction.Client. The deprecated version will likely be removed within the next couple minor revisions.

Feature: Added headers param to request

Feature: Added with_patched_client test decorator

Brought unit tests up to 100% coverage (yay!)

Sphinx-ified the docs, added to RTD

Removed Python 3.2 support (causes unit test breakage right now and I don’t really want to spend more time on it ;)). The client code should work fine, it’s just a test that doesn’t pass right now.

Added refresh_token, defaulting to None instead of dynamically adding it to the client instance

Python 3+ support added

Updated request to support a full range of HTTP methods (was previously POST and GET

Added support for multiple token transport types: HTTP headers, GET params or custom callable

Added exclude param to request_token in order to prevent certain fields from token request

Removed query param from request. These should now be added to the base url.

Added support for refresh_token

Removed check for endpoint errors in request_token. Client code should deal with that before calling request_token.
