Title: Allow S3 anonymous requests per-connection.

- add "anon=False" parameter to S3Connection object.
- using anon=True requests s3-anon auth capability.
- new Anon auth handler implements s3-auth capability.
- anon=True overrides any credentials in the environment,
config or indeed passed in on the connection.
- normal requests without credentials still fail as
anon=False is the default behaviour.
