Api spec update

Hey, Adrian:

As I've been working on the DB I've though of some API response schema changes I would like to make.  This is alpha, but I wanted to bring it to your attention ASAP.  (I wanted to discuss it tonight, but weather/traffic had other plans.)  I'm not sure how far you are with the front-end, hopefully not to far.  Take a look and let me know what you think, we do need to discuss this as I want to explain my reasoning.

I expect this to fluctuate more as the DB schema solidifies and we find all the gaps we didn't think of.  As such I renamed the API to v0 with the intention of promoting it to v1 once we get some working integration.

Let me know what you think, I would like to discuss this the next time we meet.
