Sean Feng 18ee907a90 Bug 1532644 - Implement the initial version of the Javascript Validator for ORB r=farre,smaug
For things that can be parsed as Javascript, we need to figure out
if they are JSON, and we want to block opaque JSON resources for ORB.

This initial version just checks the first byte of the response, and
blocks it if it's a curly bracket.
