@1aurabrown => add more models, show full integration of HTTP -> JSON -> Models

More work towards getting out objects ORM'd. It's not pretty code, but no-one seems to have solved the JSON ORM issues and I'm definitely not going to try tackle that problem. For now it's good old fashioned brute force.

` Kiosk/App/Networking/RAC+JSONAble.swift` still `SEG_FAULT`s. I've not figured out how to do this without the compiler crashing... Will have to try think of another way to do it. ( @AshFurrow my only guess so far is to not use a JSONAble protocol but to switch to inheritance. :-/ )

The app now downloads the sales data and parses it into Artworks when it's ran. I've not tested that stuff yet, will do so when I start to make network calls myself.
always after, I'm just playing hard and fast
