Hey there,

I've been trying to get basic authentication working as suggested in the README, but reading through the code, the only Authentication headers that are either read or set are Token based Authentication headers.

I've set authentication up op Apache2 (this works 100% certain). What happens is:

1. The client fails to ping the registry because of the 401 that Apache sends.
2. The client fails to log in to Apache because it sends a POST with a JSON with the credentials instead of basic auth headers like a normal client would.

The first issue is solved by allowing /v1/ping to the world (would need an update if ever v1 is abandoned).

The second issue is not easily solved, because it involves fixing the client.

Please either document how to use basic auth or remove the reference :)
