[crossfire] block view vs. xray vision

[Kevin R. Bulgrien]

The ground (/scorn/guilds/mailed_fist/ground) map in Scorn is made in such a way
that if you are wearing an XRay helmet you can see behind a block view "wall" to
see mechanisms that are used to make the map work.  Is this expected behavior,
and the map maker did not account for the fact that XRay might show things that
are not intended for players to see?

In this map, there is room to slide everything over and make the block view region
wider so that XRay would not show the items.  Is this the correct way to "fix" the
map?

Does XRay ever have a range greater than two tiles?
