* Update sass-rails. * FIX: Tilt dependency has been removed from Ember::Handlebars::Template. * Update `DiscourseIIFE` to new Sprockets API. * `Rails.application.assets` returns `nil` in production. * Move sprockets-rails out of the assets group. * Pin ember-rails to 0.18.5 which works with Sprockets 3.x. * Update sprockets to 3.6.0. * Make `DiscourseSassCompiler` work with Sprockets 3. * Use `Sass::Rails::SassImporterGlobbing` instead of haxxing our own. * Moneky patch so that we don't add dependencies for our custom css. * FIX: Missing class. * Upgrade ember-handlebars-template. * FIX: require path needs to share the same root as the folder's path. * Bump discourse-qunit-rails. * Update ember-template-compiler.js to 1.12.2. * `prepend` is private in Ruby 2.0.0.
