Handle URLs properly

[hgcummings]

The [https://github.com/NodeRedis/node_redis](Node.js redis client) supports (and explicitly documents) fully-specified URLs, i.e. [redis:]//[user][:password@][host][:port][/db-number][?db=db-number[&password=bar[&option=value]]].

The socket.io-redis adaptor can only handle URLs of the form hostname:port.

Thanks! The patch above is waiting for merge on PR #94. Hopefully someone can get to it soon.

That would be cool to see this patch merged.
Thanks @hgcummings for this fix.

Any chance of any movement on this? - It's becoming more inconvenient for me and I was hoping my PR would have been merged by now. Or is this blocked on issue #75?

Please let me know if there's anything I can do to help get the PR merged.
