- with the update of `ember-promise-modals` we started to get deprecation warnings when using `modals.open('modal-component-name')`
- upcoming Ember build updates will introduce tree shaking but using run-time lookup of modal components by name works against that because it's not statically analysable
- switched to importing components and passing the component class directly, eg. `modals.open(ModalComponent)`
- standardized modal component class names with a `MyModal` style to get better behaviour in code editors when it auto generates imports
- dropped the modal defaults from the modals service because we can now use a static `modalOptions` property on the modal components themselves when we want to override the defaults

- migrated install theme process to new modal system and changed to install+activate
- added "Use theme" button that opens the new install+activate modal
- when the view theme screen opens the install modal, an `onSuccess` callback is passed which sets a property that will skip closing the install modal when the view theme modal is closed and transitions to the `settings.design` route leaving the "success" modal state on screen
- added a `skipErrors` option to `themeManage.activateThemeTask` so that it can be used from processes that already handle theme errors without opening extra modals on top
