add role badges (#4029)

This adds support for the new Mastodon 4.2 role badges. Admins can
define if a role should be visible in the interface and then we get it
delivered by the Api on the `Account` object like this:
```
"roles": [
        {
              "id": "4",
              "name": "TEST",
              "color": "#ffee00"
        }
  ]
```

- keeps compatibility with older Mastodon version and non Mastodon
servers
- Took me a while, but I figured out a way to use the color and have it
look ok on all backgrounds (Mastodon itself ignores the color and just
always uses its brand color)
- falls back to Tusky blue in case no color is configured
- I adjusted the "Follows you" and "Bot" badges so they match the new
badge style
- In case the "Follows you" and "Bot" badges are visible at the same
time, "Follows you" gets its own line and "Bot" goes into the same line
as the role badge.
- Will work even with a lot of role badges (right now users can only
have 1 role at once though)
- Will work even when the badges federate (right now they don't)
