* Move publishedAtCompare to standalone function in closure scope
(allows better browser optimizations).
* Avoid getting the same field (published_at) more than once.

- implementing server-side pagination for /users API
- passing /users?limit=none will return all users
- passing /users?status=invited will filter base on user status
- creating 3 mixins (route, controller and view) to keep pagination logic DRY
- updating route, controller and view for Posts to use new mixing
- implementing infinite scrolling for Users Management screen (using new mixins)
- Users Management screen displays all invited users, but paginates active users
closes#3153
- this is all about the validation engine
- add a option, `opts.model`, to use a passed-in model directly if needed
- handle validators that return an array of strings, array of objects, or both
- ajax util returns either an array of errors or a single concat'd string
- remove formatErrors function from the mixin and make it private
- allow validation options to be passed into `.save()` since ember-data doesn't take params on `.save()` anyway
- streamline control flow
- PostsController orderBy function sorts posts with isNew to the top, otherwise their undefined dates fail to compare
- also catch when `updated_at` is undefined, happens when model is being written with results from the server
- catch objects of type Error in validation engine, helps catching client errors
- join server errors with BR tag in ajax util
- add `emberBuild` task to `grunt test-functional`
- add a test helper, `thenTransitionAndWaitForScreenLoad`, to test transitioning to major parts of the app
- add a test that transitions from Content to the Editor, and back to Content
closes#2883, closes#2951
- introduce custom findQuery in ApplicationAdapter
- posts/post route and editor/edit route now use custom findQuery to find a single post by id with query params
- create a sorting function in PostsController for out-of-order loading
- refresh updated posts in posts.index to make PostsList highlight latest draft after returning from a save in editor
closes#2414
- Add PostsController with loadNextPage action
- Collect and store pagination info from PostsRoute into PostsController
- Use `store.filter` on PostsRoute model hook to auto-update posts list template as post models are added to the store
- Add content list view and use it to check for scroll event
- Make PostRoute only load a post that's already in the store, until we figure how to load multiple pages on refresh
- Add util function from clientold that concats error messages from server response
