Included logic for reducing moves based on fields.

Unfortunately, this logic leads to some making it extremely dfficult to track move penalty exclusions, so the sludge crawler currently slows himself to a standstill with his slime.
Moved field definitions to their own header file.
Removed the speed penalty from the sludge field until the sludge crawler can ignore it.
Move final few ammo definitions to JSON.
Add tags_from_json() method to load a list of strings into a set.
Convert ammo_effects field to a tags set instead of a binary flag field.
Bind textdomain with UTF-8.
Add triffid hearts and fungal spires to the appropriate monster groups
Save/load monster group dying status properly
Make mongroups die propperly, even if the queen dies at a distance
