ASN RDF/JSON Updated

We fixed a bug in the ASN RDF/JSON where invalid JSON was produced if a literal value ended with a quotation mark (").

Example of previous bug:

{"value":"Ends with a quote/}

now correctly generates as:

{"value":"Ends with a quote/""}.

Also, URI values in the RDF/JSON are no longer string escaped. Previously looked like:

{ "value" : "http:\/\/purl.org\/ASN\/schema\/core\/StandardDocument", "type" : "uri" }

now look like:

{ "value" : "http://purl.org/ASN/schema/core/StandardDocument", "type" : "uri" }
