If you are writing a browser plugin surely its better to use a custom 
auth scheme so its not quite so hacky, also we can still have this Basic 
fallback method for users without the plugin as servers can offer 
multiple authentication schemes to a client, i.e. our custom scheme and 
also basic as a fallback.
