Fix a bug with multi-word genres in "year to date"
When clicking "science fiction" in my list of films watched in 2016 by genre (http://letterboxd.com/braindance/year/2016/), I get redirected to my diary with all of my watched films (all genres) at http://letterboxd.com/braindance/films/diary/for/2016/genre/science fiction/by/rating/
Notice the URL containing "/science fiction/". I'm assuming the problem is with multiple-word genres due to " " (though I only have one multi-word genre in the list so can't confirm).
This issue is fixed and will be rolled out next week along with our new “all-time” stats view.
