Title: Add runLoopMode property on RKRequest and RKClient. Fixes #144.

This is related to issue #144. I was searching for a way to download images while the user scrolls through a table view.

I've added a `runLoopMode` property on RKRequest which defaults to `NSDefaultRunLoopMode`. I've also added the same property to RKClient because of its `-setupRequest:` method, though it may be more appropriate on RKRequestQueue or even just exclusively on RKRequest.
