Allow boolean subschemas everywhere.
This implements issue #101, including root schemas. Also add JSON Reference objects as legal schemas in the meta-schema. Since "$ref" is now only allowed as a JSON Reference where a schema is acceptable, it can now be described in JSON Schema and included in the "anyOf" that defines legal subschemas.
