If delay is left on javascript clicks are not bubbled up

https://github.com/averyvery/trackiffer/blob/master/trackiffer.js#L186

If the link being clicked has an outbound link that is actually used to load something with javascript later on, trackiffer converts that to the window.location instead of letting it bubble up. Not sure if there is a way to handle both normal links, and links that are bound to other click event handlers.
