Closes#6390
- check if more posts should be loaded whenever one is deleted
- delete dead code from posts controller
- delete duplicate component gh-infinite-scroll-box
- simplify posts-list-item `posts.post` or `editor.edit` link logic by modifying `gh-content-view-container` to yield necessary vars directly and use inline ifs in template
- add `gh-tag` component for rendering tags and updating infinite scroll box on `settings/tags` page
no issue
- review use of Ember core hooks and add a call to `this._super` if missing
- fix a few occurrences of using the wrong component lifecycle hooks that could result in multiple/duplicate event handlers being attached
`_super` should always be called when overriding Ember's base hooks so that core functionality or app functionality added through extensions, mixins or addons is not lost. This is important as it guards against issues arising from later refactorings or core changes.
As example of lost functionality, there were a number of routes that extended from `AuthenticatedRoute` but then overrode the `beforeModel` hook without calling `_super` which meant that the route was no longer treated as authenticated.
no issue
- add ember-suave dependency
- upgrade grunt-jscs dependency
- add a new .jscsrc for the client's tests directory that extends from client's base .jscsrc
- separate client tests in Gruntfile jscs task so they pick up the test's .jscsrc
- standardize es6 usage across client
