Ember Bootstrap has changed a lot since the very outdated pre 1.0 release
which was used here. Changes are mostly about using composable components
and closure actions.
Also replaces PhantomJS with Chrome in CI cause PhantomJS is also very
outdated and causing test failure not related to any real world issues.
Ember CLI has replaced PhantomJS with Chrome in v2.15.1, which is the
upfollowing minor release to the version currently used.
ToDo left:
refactor `datetimes` property of `create-options-datetime` component to
not cause whole list to be updated. This is not only a performance issue
but also UX: e.g. validation state is lost when another item is added.
There might be use cases and it simplifies validation a lot.
Also fixes this missing translation message mentioned in #84:
> /create/options-datetime: There isn't any validation error shown when validation fails due to not enough times.
