Fix global leak of ret in JSONPath.normalize().
While writing mocha tests around some use of JSONPath, it found a global declaration of ret in normalize() versus var. There appears to be no reason why ret would be a global in this context, and in other versions of the codebase--on google code--the value is just returned raw because there's no caching in place anyway.
