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
closes#6018
- added keyForAttribute method in application serializer
- override keyForAttribute in settings serializer to not apply camelCase/underscore conversion
- rename under_scored properties to camelCased
refs #5798, closes#5018
- adds new `gh-fullscreen-modal` component - modals are now specified in-context so that they can have deeper interaction with their surrounding components/controller/route, i.e. a modal component can be a thin confirm/deny wrapper over the underlying controller action keeping all context-sensitive logic in one place
- adds spin-buttons to all modals with async behaviour
- adds/improves behaviour of inline-validation in modals
- improves re-authenticate modal to properly handle validation and authentication errors
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
