Access to Conversation participants permission

[Morgain]

I want to restrict one of my usergroups to Conversations only with their own usergroup.
Plus admins.
This is a small usergroup of only 5 with 2 admins so I could do it per user.

Explanation: This is a staff group. But they keep doing far too much support work in Conversations and not using the forums.
At the moment I have had to disable Conversations for everyone

So I want this staff group to be able to contact each other, or Admins.
But they cannot contact anyone else.
No one else can contact them.

You will need to extend this function:

XenForo_Model_Conversation::canStartConversationWithUser

From there you can check the user info for both the "to user" and the viewing user.
