Collaborative Threads 2.11.1

• Support for Attachment Improvements per-forum size/count permissions
• Thread Starter Alerts integration

• Add 'Always Collaborate' permission, respects the "Participate in collaborative threads" permission
  • If a user is added as a collaborative user, they pickup whatever group they are given. Otherwise defaults to the built-in "All" group.
  • In a forum without "View Others" , the 'Always Collaborate' does not result in all thread's being listed. Non-visible threads are still directly accessible, they just don't appear in the list.
• Implement "Allow post collaborators to view edit history" option (default disabled)

• Support Threadmark Index permissions (Require Threadmarks v2.0.1)
• Avoid N+1 query behaviour if the post's user isn't loaded
  • Thread & post bbcode add-on compatibility fix

• Support for Threadmarks for XF2
