@ashfurrow => place bids & real card swiping

(looped well!)

* So we have to use this crazy init func: `CFTReader(andConnect: ())` in the library, so previously it wasn't working, now it should be using the card reader for realsies.
* With that in I wanted to get bidding working, so I added a new view controller which exists to show the "placing a bid" and then moves into a different VC once we've confirmed you've either won or lost.
* Moved all stubbedJSON into their own folder

Again, should coalesce here (and below as well). The docs for `then:` say:

> This block must not be nil, and it must not return a nil signal.
