[setchy]

Closes #1367
Closes #1368
Closes #1369

Enhances the account management module to:

• Support account refresh (user data and platform version) either:
  • manually via account management screen
  • schedule (daily)
  • on application startup
• display account avatar on
  • account management screen
  • account notification row
• reorganize account notification row layout to
  • display account avatar
  • add platform icon and "quick links" (my issues, my pull requests) as account notification interactive buttons on hover

Does it make sense to keep the links in the left nav on these situations?

I was wondering about the same.

I think with the addition of #1436 it still has value for now. We can reassess as we get more hands-on with this.
