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!

Aaah, but then what about all those PRs!!!1!

(actually doing this wrapper thing, adding it is just way tooooo inexpensive for me to just leave it out)
