Improve accessibility for people with red-green colourblindness

[ThatBlockyPenguin]

Proposed change

The icon used to communicate whether an addon is running or not is currently just a circle, and we rely on colour to communicate its status. This PR changes that, and makes the icon change when the addon starts/stops. This makes it easier for people with red-green colourblindness (like myself) to see at a glance, the status of the addon.

Any particular reason why you choose mdiCircleOff for stopped instead of mdiStopCircle?

I was concerned it may look like a button to start and stop the addon, so I looked for alternatives. I couldn't find an icon I liked for "running" that was circular, other than that play icon, but mdiCircleOff was available for "not running" and I think it conveys an "off" state well. If you have any other icon suggestions I am open.
