Subject: Fixes #1088: Show number of group members. Unlike the bugreport
 requested, the stats are displayed similar to userstream stats in a section
 in the sidebar. Additionaly, I removed a redundant notnull if check in
 ShowgroupAction->showMembers, fixed a SQL error in User_group->getMembers
 when no limit is passed, removed return value storing of void function and
 added an usage of Profile->getBestName.
