@ashfurrow => more changes (NEEDS SNAPSHOT UPDATES)

I expect this will fail, I can't see the snapshot diffs in Kaleidoscope or Xcode. Not sure how to deal with that.

* Weird window setup was happening because we were using UIScreen.mainScreen.bounds() for the frame of our UIWindow, which doesn't work in Portrait mode. (screen bounds don't reflect orientation while window bounds do)

* put the proper button and textfield classes everywhere in the storyboard

* #minor: rearranged the storyboard to make it easier to navigate at (in my opinion)

* change to Masonry artwork cells to display current bid price in the proper font, matching designs. (Couldn't figure out how to do this as one label with an attributed string)

* change all custom buttons to be of Custom buttonType to avoid tintColor affecting Highlighted state
I missed this on my first pass – if there was something weird going on with our bounds, we should make a comment. Also, I prefer to use `CGRectGetHeight` and `CGRectGetWidth` because they normalize their return values (so that they're never negative).
