Trigger angular digest cycle within amTimeAgo

[matthewdfleming]

So amTimeAgo auto updates the 'text' of the element with the directive using a $window timeout. Could you fire a scope.$apply after things are good, to notify angular of the changes?

We don't do this as this will negatively impact the application performance for many of our users (for example, see #8). What is your use-case?
