Restrict who can use what visibility settings

Currently, visibilities and management permissions have no link. In other words:

• If someone has edit permission they can create content for any visibility
• If someone has publish permissions they can publish to any visibility 

That's annoying because writers often select the wrong visibility permission.

I'd like to give lots of teams the ability to publish content that's visible to their area alone. That would roll Guide out across the organisation really effectively.

But I can't, because I can't trust people will publish things to the right audience.

So I'd like to restrict who can publish to which visibility.
