Bug #1006634, part 3

In many places user urlids are not currently available when the
profile url is generated, but it is trivial to get it, and then change
the user/view.php url to a profile_url call:

- Admin page access report
- Profile links in feedback lists
- My friends block
- Wall posts
- Group members block
- Group members tab
- Recent forum posts block
- Group admin lists on forums page
- Group admin lists on my groups, find groups
- Group admin lists in group info block
- Profile sideblock
- My friends & find friends pages
- Institution landing page
- Online users page
