Merge lp:~rharding/lazr.restfulclient/basic_auth into lp:lazr.restfulclient

[Richard Harding]

Implement the authorizeRequest for the BasicHttpAuthorizer.

= Summary =
The BasicHttpAuthorizer has a method to auth a request with basic http auth,
however it wasn't implemented. Only the method for auth'ing a session was.
This adds a working method to add the correct header.

== Implementation Notes ==
Basic http auth is just the username:password base64'd. This implements that
into the authorization header.

== Tests ==
Added a new doctest to hit this specific method. It doesn't fit the 'flow' of
the current doctests, but just wanted something that verifies it encodes
properly.

Tests run via buildout:

./bin/test

This looks fine.
You need to update NEWS.txt and version.txt before packaging and uploading to pypi.
