Add Interface::display_area_stats(AREA_HUNTING_CAMP).
Include animals when generating the city map.
Macro for defining animals in a terrain type.
Change all references to "game" to "animals" to avoid any confusion.
Two new animals: jaguar and akhlut (Inuit legend, half orca half wolf, amphibious).  New struct Animal_amount holds an animal and an amount, with a few functions for adjusting the amount randomly.  Animal_datum now holds a pluralized name.  Function animal_amount_ranking() returns a string to describe the size of an Animal_amount (e.g. "a pack of" or "uncountable").
Move text_map_info up one line and make it one line taller.  This is experimental, I'm not sure it'll look good.
Tweak Interface::display_area_stats(AREA_HUNTING_CAMP).
Terrain_datum and Map_tile hold Animal_amounts instead of Animals.  The actual popuation of the animal there.
Add animal data.
New function World_map::animal_count().
