Use JSON.parse instead of deprecated goog.json.parse.

Thanks to [] shared libraries at Google now produce valid JSON which allows using JSON.parse. It is safer and faster than goog.json.parse which uses eval by default.

NOTE: All shared libraries producing JSON at Google were changed to produce valid JSON. However, if your code uses a custom way of producing JSON (not using the shared libraries) or if your code parses JSON generated a long time ago and stored, this CL might break you so please review with care.
