[Freeciv-Dev] Rules changes

[Per Inge Mathisen <per@xxxxxxxxxxx>]

After some discussion on IRC, I decided it was time to change the
following in the default rules
 - Remove the risk-of-losing-units flag from glaciers. This is just
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.
 - Combine city walls and coastal fortress. The coastal fortress as it is
now is way too expensive, is not shown on the map, and comes too late in
the tech tree to be useful against the first waves of oceanic attacks.
Also the city wall is not as useful as it ought to be.

Speak up if this will not be well received.

Once I get some more time (soonish), I will also make a new ruleset for
quicker online games.
