generate types from graphql queries

[kevinhughes27]

Changes:

• use a fork of relay (soon to be merged Language plugin support. facebook/relay#2293) to generate typescript files from relay instead of javascript
• I added my own script to copy these types to the global types folder so that I don't have to include them everywhere. Its a bit less explicit but the relay type names are super obvious so I am okay with it.
• I updated a lot of always present fields to be null: false in the API spec. This creates some issues with interop with the old admin that I found a new work around for.
• I also changed the API to use plain ID fields in a few places. For CRUD actions its nicer on the client to use the plain ID
• I changed the API to only return fields with maps and made the types non null
