Consolidate user redirection #260
Description
Follow-up to #220: Remove the "In Gruppen" section from the user page and move the reload logic to the request target (i.e. "force navigation") dropdown.
This dropdown now has 3 key items:
- Shows number of group members currently online.
- Reload page for all users in a group (with confirmation).
- Navigate all users in a group to your current page.
Consider changing the icon to something that represents either "class" or "user redirection". Also consider putting that dropdown right next to the switch user dropdown.
