[IMP] website_slides: add next lesson field to membership

Before this commit,
There is no way to see the next lesson of attendee.

After this commit,
User/Manager can see the next lesson from backend.
Also added 'is_published' field into course's tree view.
Added search for responsible, tag and content, also added 'Archived' filter.
