Update rs_id.json

I added db_codes of db_xref in insdc, which are available in Identifiers.org.
# mapping data the following URL:

Bug fixed in json format.
Fixed rdf:type for exon, introduced sio:is-transcribed-into for gene and mRNA relation
Fixed that sio:is-transcribed-into was misplaced
Added support script for virtuoso
Fixed and updated
* Fixed to use exon URIs instead of part URIs for exons referred to by parts.
* Changed to use INSDC feature keys instead of SO ID for feature URIs.
* Removed SO ID from FALDO region URIs.
* Changed to use URI instead of QName for sequence_id.
* Changed to use NCBI URI for FASTA sequence instead of the TogoWS version.
* Fixed critical bug in representing relations between mRNA/CDS and exon following the RDF summit guideline
* Fixed bug in handling faldo:FuzzyPosition
* Refactored code on generation of FALDO region/positions
Biologically critical issue that multiple CDSs located on the exactly same location can't be distinguished is resolved by adding serial ID to each feature
Fixed that isql doesn't understands \n as new line.
Use skos:prefLabel for gene names in addition to rdfs:label
Use skos:altLabel for gene_sysnonym
Updated to include ensembl2ttl etc.
Minor fix
Give a better positional range URI to feature having joined segments (exons).
Added links (owl:sameAs, rdfs:seeAlso) to other Taxonomy ontologies
Changed to follow recent agreements with the Ensembl RDF model to define each feature as a sub-class of SO classes, use sio:is-transcribed-from instead of sio:is-transcribed-into, use ro:in-taxon etc.
Also, features are typed by classes defined in the INSDC ontology, introduced a virtual sequence URI (#sequence fragment) to be separated from entry URI, changed to use insdc:topology and obo:so_has_quality for describing linear/circular sequences, use obo:so_has_part for exon URIs and sio:has-ordered-part for individual part URIs (which sio:refers-to exon URIs).
Updated to add classes from the INSDC ontology
Added descriptions and license for the generated ontology file
Changed INSDC/DDBJ ontology location for release
