Generate unique icons for profile icon

[keyserj]

Is your feature request related to a problem? Please describe. The user profile icon does an ok job of indicating that the user is logged on, and that it can be clicked to view user-specific things, but since the icon is not unique, it doesn't do a great job.

Also, in the future we'll want to have somewhat-unique icons for users anyway, so that things like comments can be visually identified.

Describe the solution you'd like Each user should have a unique profile icon! It seems easy enough to generate something almost-unique based on the user's username. This https://ui-avatars.com/ seems perfect!

Technical ideas

• eventually we'll want to store something in our DB for this so that users can customize the icon, but for now just a generated one seems fine, so it seems reasonable to just rely on making a request to ui-avatars every time the icon needs to render (maybe something like this that we do in the docs)
  • since the icon currently only renders in the Layout, requests shouldn't happen that often
  • if we end up making a lot of requests, we can always cache the request too
• it looks like ui-avatars doesn't generate background color based on username, so we might need to do find another library that does that?
  • looks like https://avatars.oxro.io/ does have name-based background colors, could potentially use that
