There should be a terrain flag TER_NO_CITIES.  This should be given to 
ocean and maybe arctic.  (This is unrelated to this patch.)

You should also add an exception to the code (unit_loss_pct) for tiles 
with cities.  A unit should never be lost on a tile with a city.  This 
applies for tririemes on cities in deep ocean also (current rulesets 
don't allow deep-ocean cities; so what).  is_pos_dangerous may also need 
to check for cities.

There shouldn't be any huts on the arctic (TER_NOHUTS?).  The rest 
should be handled by TER_NO_CITIES.
