Upgrade to Ember 1.11-beta.1 HTMLBars goodness! Since there was some breakage and a lot of fiddling around to get some things working, I took this opportunity to do a big cleanup of the whole Ember app. I accidentally worked on some new features too :3 Note that the app is still broken right now, pending on https://github.com/emberjs/ember.js/issues/10401 Cleanup: - Restructuring of components - Consolidation of some stuff into mixins, cleanup of some APIs that will be public - Change all instances of .property() / .observes() / .on() to Ember.computed() / Ember.observer() / Ember.on() respectively (I think it is more readable) - More comments - Start conforming to a code style (2 spaces for indentation) New features: - Post hiding/restoring - Mark individual discussions as read by clicking - Clicking on a read discussion jumps to the end - Mark all discussions as read - Progressively mark the discussion as read as the page is scrolled - Unordered list post formatting - Post permalink popup Demo once that Ember regression is fixed! 2015-02-10 18:05:40 +10:30			`{{#if target}}`
