refs TryGhost/Ghost#7865💄 refactor signup to use ember-concurrency
refs https://github.com/TryGhost/Ghost/issues/7865
- moves authentication actions from `signup` route to controller

- replaces use of `gh-spin-button` with `gh-task-button` in signup template
💄 refactor setup screens to use ember-concurrency
refs https://github.com/TryGhost/Ghost/issues/7865
- moves authentication actions from `setup/two` route to controller
- refactors authentication and setup logic into EC tasks
- replaces use of `gh-spin-button` with `gh-task-button`
- fixes some styling issues with the new SVG icons
- adds `app/styles/patterns/icons.css` back to contain per-icon overrides and animations (some SVGs use fills and others use strokes so we sometimes have conflicting styles)
closesTryGhost/Ghost#8107
- replaces all icons in Ghost-Admin with SVGs by using our new helper {{inline-svg}}.
- removes all ghosticon fonts.
This is the second and final batch of the refactor.
refs https://github.com/TryGhost/Ghost/issues/7515
- add a `retry` icon that better matches button text dimensions
- add a spin animation for the retry icon
- use the new retry icon in the default `gh-task-button` template
- add a "restart animation" method to `gh-task-button` so that repeated clicks on a button appear to register the action when local validation means that there's no transition from failed->running->failed
refs https://github.com/TryGhost/Ghost/issues/7515
- adds animated spinner and check SVG icons
- improves SVG sizing/alignment in buttons
- disables old technique of fixing button size because it doesn't work now that buttons have more than a single spinner when running/saved/failed
- fixes broken spinner in `gh-spin-button` components
Update for synchronous feature service
Add client-side handling of server-side errors when adding subscribers
- display server-provided error message when we get a server error
- fix the ajax util's `getRequestErrorMessage` method so that it works correctly with Ember's `InvalidError` object instead of the previous request object that it was receiving (*TODO:* this really needs looking at properly so we aren't losing details and Ember Data can do it's stuff)
Styling updates
- proper icon for ascending/descending
- change hover colour to green for "Import CSV" button
Delete subscriber button with confirm modal
- display delete button when hovering over a subscriber row (WARN: really ugly button, styles definitely want looking at)
- show confirm modal when clicking the delete button
- delete subscriber, remove from table, and update total on confirm
