Request: additional text output columns

We currently have entertext and leavetext, but no method for sending a specific message when certain actions are denied. I propose adding: * protectedtext - text to show when someone tries to build in a protected area, and is denied * restrictedtext - text to show when someone is denied entry to a restricted area

These are the only functionality of the old Cuboid we're missing in lionsArea, and these two would be very helpful to have in some situations.
