python-demjson: new package

demjson is a Python JSON module that reads, writes and validates
JSON-encoded data; compliant with RFC 4627.

It also includes a lint checker, jsonlint, which can be used to validate
JSON documents for strict conformance to the RFC specification; as well
as to reformat them, either by re-indenting or for minimal/canonical
JSON output.
