add new permission to show claim dimensions

Show the claim size to those with griefprevention.seeclaimsize when right-clicking with the investigation tool
(stick by default) - it's not exactly private information, the claim boundaries
are visualised so it would be easy to just count the blocks or compare the
coords of the corners to find out.
