log_outgoing interferes with other js click events

[mjangda]

If I add a click event to a click after wp-google-analytics has loaded which calls preventDefault or stopPropafation, log_outgoing tracking will send the user to the link anyway since it fires first and sets a timeout.

Thanks Mo. Unfortunately I likely won't have a chance to look into this for a few days. If you or Daniel get to it before me though, I'll get the pull request merged right away.
