About Forest and Ices
some terrains can have a flag "forest" to be handle separatly. maybe
there is not needed to handle it as a spetials.

about ice i need at last 2 type of ice, one on land and one on ocean. if
not handeld as a spetial this will be in a terrains type with, then
 
clima = ice OR (a list of) cold, temperate, tropical.

then minimu set of terrains need 4 more

[plain ice]
relief= flat
clima = Ice
wetness = dry, medium, wet

[hill_ice]
relief= flat
clima = Ice
wetness = dry, medium, wet

[sea ice]
relief= flat
clima = Ice
wetness = oceanic

[ocean_ice]
relief= flat
clima = Ice
wetness = oceanic

then in code side this need a TER_ICE and a TER_FOREST
specialy case is a TER_ICE && TER_OCEANIC most naval unit can't travel
there. but is more easy to handle in generator if i can assume allway
exit even if stat are the some for all ice types.

These infos can be add from now in ruleset, to beigng convert
generators,, this is not a shrot work, as there is many generator
working in different ways
