Type missing from schema

[bgburton]

I have been validating the 1.3.0 schema with a json validator for an R project. It says that the schema is missing '"type": "object"' in several places, always before a properties field. This occurs directly within "additional_col_properties" and also within any of the "allOf" fields. The following appears to work. I only raise this because the schema will not validate without the corrections.
