Improve global back button. Goes back to previous interface. It’s not quite like the browser’s back button because it doesn’t necessarily go back to the last URL; rather, it goes back to the last interface. So if you go into a discussion, then go to a different discussion via the side pane, the back button will still take you back to the index (not the previous discussion). 2015-03-20 10:40:42 +10:30			`import Ember from 'ember';`
