enable watchedAt tooltip 

SchizoDuckie:
The goal was to alter the episodeWatched.js directive so that the Green Eye tooltip would display "You marked 
this episode as watched on 25/06/2014 10:00 am" in the appropriate locale language and date format.
But I cannot seem to find a way to parse the tooltip through the date:'medium' interpolation.
For now I've defaulted to using a variation of the prior "new Date($scope.episode.get('watchedAt')).toLocaleString() logic.
Any suggestions ?
