WORLDGUARD-3299 - Reported by B1acksheep

As discussed in IRC:
Snapshot 6.0.0

Global: Interact allow (to use doors, pressure plates and interact with animals)
Town: Interact nonmembers deny (prevent interaction of nonmembers with the property of the town)
User-Zone (Region inside Town): Interact nonmembers deny (prevent interaction of nonmembers with the property of the user)

But if a user is member of the „User-Zone“ and not member of the Town, he can’t interact with his own property.
We can say: User-Zone:interact members allow, but if the region is not complete inside the town, there is no protection against interaction.

I guess a „interact members allow & interact nonmembers deny“ would be an idea, but the docs said its not possible.
