Closes#6440
* Removed the `.fake-placeholder`class from the input, test, and css
* On adding a nav item, if the url value has not been set by the user,
then set it to the base url as shown in the input
* If url has been set by the user, just do what it has always done
refs #6458, closes#6457
- replaces jquery-ui.sortable with ember-sortable for drag-n-drop handling
- moves the "new/blank" nav item out of the nav items list
- allows it to be excluded from the draggable list
- cleans up handling of the `navigationItems` array as there's no longer a need to ignore/exclude this extra item
- clears validation errors when typing in the respective field
- adds acceptance test for adding/removing nav items
- improves acceptance test for saving nav items to cover more edge cases
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
refs #6039
- adds ember-cli-mirage dependency
- sets up mirage to match our API endpoints and responses
- adds fixture data for settings that are always present for all blogs
- converts existing acceptance tests to use mirage
refs #5845
- Updates tag settings screen to match content screen behaviour. Each now tag has it's own route that is link-able from other areas of the app
- Updates a number of places where jQuery event handler code was not wrapped in Ember's run loop
no issue
- increases the timeout because acceptance tests sometimes hit the limit which then caused a knock-on effect through other tests
- fix settings/navigation acceptance tests where it picked up previous test failure error messages
- fix user model unit tests so that `expect` is always called _after_ the runloop has finished handling property updates
no issue
- update grunt-jscs dependency
- fix deprecated `validateJSDoc` configuration
- fix numerous linting errors, including:
- use of future-reserved `public` and `private` variable names
- use of `[]` instead of dot-notation (especially `express['static']` and `cacheRules['x']`)
- extra spaces in `const { run } = Ember` style constructs
One issue that did become apparent is that there are conflicting rules that prevent the use of object function shorthand such that both of these:
```
{ myFunc() {} }
{ myFunc () {} }
```
are called out due to either the missing or the extra space before the `(`
closes#5852
