* New feature: users can rate support answers
Now users can rate support answers. They will see links "This is good answer" and "This is bad answer", like it was in original VK.
Changes:
1. Add the ability to display only administrators on the page with a list of subscribers
2. Add the ability to hide the fact that the subscriber is an administrator
3. Fix display of large text in the block with the list of administrators
4. Fix display of the number of administrators
This commit allows you to pin groups to the left menu (max 10 groups, only those in which you are the administrator) from the My Groups page. Fixes#186
This commit allows you to display the list of administrators instead of the group author (maximum 7 administrators, the rest will be hidden) and hide the group author
