Negative integers not supported

[shauns]

Negative integers are not validated correctly:

select validate_json_schema('{"type": "integer"}', '-103948');
 validate_json_schema
----------------------
 f
(1 row)

I think the answer is to look at the type check where data is coerced to text and compared to a regex -- I'm not sure what's most performant, but maybe there's a built-in function to fulfill this check.
