Wrap util.js in an IIFE to prevent deploy error

'use strict' can mess up execution of third-party scripts if
they are all concatenated to the same file. To prevent this, code
is wrapped in an immediately-invoked function expression (IIFE).
This ensures that the strict mode is only applied within the scope
of the function it’s wrapped in.
