Show community account last login and count info on admin page

mhagander · mhagander · commit e850a9bf3e08 · 2020-07-07T12:25:39.000+02:00
The collection facility was added in
[200~9e70a4e0c32f8db0178f05dac4c1fca7b317e7c5, but no way was added to
view it. To make it a  bit more useful, add a static set of info on the
user edit page in /admin/ that shows the last login and number of logins
per site.
