As title says goal was to add administrator link to top menu. To make this possible we made several changes...

• added an administration link in top menu
• moved logout to user menu, we know this is kinda an anti pattern but it should be ok as users can decide whether login should be remembered. We did this to keep the top menu small as we added the Admin link
• renamed some settings links in admin menu (removed the duplicated "Settings" wording)
• Moved the hardcoded login/logout links out of the template to a Menu class. This allows plugins to add the logout to the top menu again and to remove it from the user menu etc

After merge: We need to add new translation key to oTrance: General_General and UsersManager_AnonymousUser
