Rename FIELD_TYPES to FIELDS
Remove unnecessary forward declaration of Field & Field_type from map.h
Add support for loading Dice that are just a single number - for static values
Added some more stuff to docs/todo.txt
Add new damage type - Fire.  Common enum Terrain_flag.
Add "flammable" flag to items.
Change Field fuel damage to a Dice.  Permit Field damage to hit "all" - shorthand for all Body_parts.  Rename "damages:" to "parts_hit:" in Field_level.  Fix incorrect check for Field_type spread_cost that constricted it to [1,100].
Add data/fields.dat - Field data
Fix error caused by chomping after loading Dice (don't do that).  Field_type now has its own flags which apply to ALL levels.  Better error warnings when loading fields.
Map::add_field(Field_type* type, ...) warns and returns false on a NULL type.
Fix an error in field.cpp, add debug function to game.cpp - ! now spawns a fire (doesn't work???)
Stuck a bunch of debugmsg all over to help me debug fields - not done with them yet, so they'll stay in for now.
