Switch to using $ instead of # for sub-types

# is reserved by the swagger validator as a way to include partial content from a JSON object (eg: "#/path" would include {"test": true} from the object {"path":{"test":true}}). Instead of trying to convince the validator that it is wrong, we'll just use a different character.

Note that our rendering tools do not care about #-style references to objects. It's still somewhat worth changing the character though.
