Sidebar-Headline on user and group pages does not wrap

[Former user]

on /user/someone and /group/somegroup a longer realname does not wrap properly in the sidebar. Example: http://www.biblicious.org/user/2sr.

This needs to be checked and eventually fixed also on other pages which use the same headline structure.

Will be fixed in my sidebar branch. Basically we should not use the (uncontrolled long) realnames in headlines. We should use consistently the usernames or groupnames and present the real names as extra property

fixed with merge of sidebar branch
