exposing all redis methods (incl. EventEmitter)

Hi @apechimp !
I ran into a situation where I needed to respond to error and connect events, but found that those where not actually exposed. This PR exposes _all_ redis methods.

Thanks!

Ohhh! I like that. I'd ultimately like to remove the dependency on `node-redis` because no one should ever trust me to keep this pinned to the correct version of the `node-redis` for their application.
