Commands with 3+ arguments don't work

[danhunsaker]

I attempted to use SETEX and found, to my dismay, that it wasn't getting all of the arguments it wanted. Upon inspection of the __call() method, I quickly discovered why. I have a simple fix for this, which I will issue a pull request for in just a minute. I don't think it will fix Issue #18 (though it might provide a cleaner workaround), so I'm creating a new issue for it here.

Basically, the fix is to use implode() on the arguments array, since the logic in _encode_request() already properly handles an argument list separated by spaces. This is only done, of course, if the first argument is not an array. The second argument to _encode_request() is not sent in this case.

Closed per #20. Thanks again.
