Subject: [PATCH] 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.
