Subject: [PATCH] jsonMessages: basic schema for JSON APIs

JSON APIs are ubiquitous. This schema allows for reusuable
connectors that translate Preserves to and from JSON endpoints.

This schema contradicts the current JSON schema described in the
Preserves spec because it uses symbols for object keys rather than
strings.
