Adding enum values in the property editor does not update the schema

[bwesterhaus]

If loading a schema with enum values, they are loaded into the property editor, but adding enum values or adding an enum to a property that does not have one does not update the schema.

@bwesterhaus Thanks for flagging this. Itn has the same underlying cause as https://github.com/jackwootton/json-schema/issues/67

I'll leave this open for verification purposes.
