Extend /is settings to both coop & visitors

Old idea: A menu to select what will the coop player be able to do

New idea: Like Landlord

In the /is settings, the leader will be able to select what the cooped players and the visitors can do.
(Purpose: avoid destruction while coop)

I don't like this - too complicated.
