Authentication should be removed

[elfey]

With the new feathers-authentication-client, authentication isn't really necessary in this module. This module is now, for the most part, kind of a "networking" module for connecting the client to the server (as opposed to authenticating).

So it would make sense that we remove the authentication bit from this module. (i.e. feathersClient.authentication because it's being replaced with feathers-authentication-client).

@mz103 the intention of this module was originally to provide all client modules in one place. All other modules would be at feathers-module/client.

I think we will keep it like this for now (feathers-authentication-client will still be feathers.authentication). It will all make more sense in the next version when we tackle #137. I still don't know how I feel about browser builds for each individual client module but maybe that is the best way to do it to avoid any more confusion on what is included in the client build.

Closing this for now.
