It's stalled but not burned.

1.  It should be a terrain flag (T_DANGEROUS?), not a hard-coded use of 
T_ARCTIC.  We have terrain flags now so this should be no problem.

2.  Tririemes near arctic should also die.  For now we can do this your 
way, by skipping over T_DANGEROUS tiles in is_coastline.  (But are you 
sure is_coastline isn't used anywhere else?)  But soon we should do this 
by introducing separate ocean terrains.  For this we'll have problems 
using simple terrain flags because it's not a boolean state.  So I think 
we need a new terrain integer danger_level.  Units under this level will 
be in danger when crossing this terrain.  Then we can have 2 (or more) 
ocean types: shallow ocean and deep ocean.  So then we have to change 
mapgen to (usually) put deep ocean near arctic.

For changes to the default ruleset we have to turn to the design board.
