[Freeciv-Dev] (PR#14555) Glacier rules change

["Per I. Mathisen" <per@xxxxxxxxxxx>]

<URL: http://bugs.freeciv.org/Ticket/Display.html?id=14555 >

As discussed previously, here are some changes to the glacier terrain. You
can no longer build cities on top of them, but they are no longer unsafe

confusing and annoying. Also the AI loses units left and right to it
under some circumstances, since it does not understand it.
 - Add a no-cities flag to glaciers. Guess I'm tired of seeing those
sprawling cities on top of nothing but ice.
