Upgrade messages are now shown on the About screen rather than as alerts. Notifications that are marked as `top` or `custom` are still shown as alerts to allow for certain upgrade messages to be given more visibility.
- remove old `upgrade-notification` service
- update the `upgrade-status` service:
- add a `message` property that contains an upgrade notification if any exists
- add a `handleUpgradeNotification` method that accepts a Notification model instance and extracts the `notification.message` property into a html safe string for use in templates
- when loading server notifications during app boot, pass notifications that aren't marked as `top` or `custom` to the new `handleUpgradeNotification` method
- update the `about.hbs` template to pull the upgrade message from the `upgradeStatus` service

- detect iOS devices and start a requestAnimationFrame loop when inserting the markdown editor that watches `body.scrollTop` and translates the scroll that iOS applies to the body to the editor instead so that we keep the cursor on screen without the disconnected cursor proplems

- using an `<a>` element to parse a URL does not behave as expected when the URL has special characters because the `host` attribute will show the Puny URL version. Eg. `exämple.com` will become `xn--exmple-cua.com`
- `{{gh-navitem-url-input}}` was failing to manipulate the URL value because of the difference between the Puny URL encoded URL and the raw configured URL with unicode chars
- uses the `URI` module that's bundled with the imported version of `google-caja` to parse the URL via regexes rather than relying on native browser parsing

- `{{vertical-collection}}` causes async issues and random failures in our tests
- we can't upgrade to the latest version which includes a test wait helper because it's buggy in Firefox
- skip the tests for now

- in `{{gh-cm-editor}}` display a standard textarea in place of the CodeMirror editor whilst CodeMirror assets are loading in the background, textarea will be upgraded to a CodeMirror editor when loading finishes
- update styles so that the switch from plain textarea to CodeMirror is not too jarring
closes https://github.com/TryGhost/Ghost/issues/9356
- it was possible to start a selection from outside of CodeMirror's control, this was confusing because text appeared to be selected but wasn't
- disable user selection on the outermost CodeMirror wrapper so that the selection behaves as it does with a normal textarea where the selection needs to start from inside the content area

- adjust weekday and current day text colours in the calendar popup to improve legibility
- match the new tags input colours to the other form inputs

If a user is trying to use the split screen preview shortcut in the admin client (`CTRL+ALT+P` for all platforms), this also calls the publish shortcut when using windows or linux.
- change the publish shortcut to `${ctrlOrCmd}+shift+p`
no issue
- `Ember.testing` is or will soon be a getter/setter in Ember with the value set during a test, however destructuring will read the value when the module is evaluated
- moves all uses of `Ember.testing` inline

- don't use `dataTransfer.effectAllowed` in IE11
- only fire the action in `{{gh-file-input}}` if there are files selected to prevent a double call to the action due to resetting the input
closes https://github.com/TryGhost/Ghost/issues/9298
- override the default Ember Power Select behaviour of stopping keydown event propagation for any alpha-numeric key events which was preventing our keyboard shortcuts from being triggerable

- as of d33cfdac30 we reset the file input earlier in the actions chain, this was clearing the file references before the editor was triggering the upload. By converting the `FileList` to an `Array` before resetting the input we keep hold of the file references and the upload works again.
