    Add async.nextTick browser fallback to setImmediate
    
    This adds the nextTick fallback for browsers to support
    the proposed setImmediate interface, which is similar
    to process.nextTick in browsers that support it, or on
    sites that implement a shim for setImmediate before
    loading async.

 This is used internally for browser-compatibility purposes.
