* Don't reference the notification levels by colour
We're about to change what colours they are so either we'd have to rename
a bunch of constants. We may as well make things not reference what colour
anything is in the actual UI. Hopefully these constants are clear enough.
* Rename NotificationColor -> NotificationLevel
* Red -> Highlight
* Grey -> Notification
* Bold -> Activity
* Anywhere else that calls it 'color' -> 'level'
Also fixes some weird mixes of US & UK English.
It turns out this is referenced in... quite a lot of places, so this is
quite a large PR. It can't really be much smaller, sorry.
* One test rename & some hiding due to ts-ignore
* More hiding behind ts-ignore
* Damn you, @ts-ignore...
* Fix test CSS values
* Missed some colour -> level
