Title: allow cache-breaker params in EscapedParams

EscapedParams was raising exceptions on URLs with cache-breakers. After giving it some thought, I couldn't think of why anything but a String, Array or Hash would be passed through. So I've removed the ArgumentError exception raise and am instead returning nil which allows the parameter to pass through properly.
