- IF_FIELDS (formerly IF_OBJECTS) can now deal with any kind of field (apart from special spots, which aren't technically a field but share some implementation details).
- The twelve RECT_PLACE_XXX field nodes (well, one of them was RECT_CLEANSE) have been collapsed into one, allowing the placement of any kind of field (apart from special spots). In particular, antimagic fields can now be placed! (There wasn't a node for them before.) As a bonus, since it exists in the field type enum, RECT_PLACE_FIELDS can also smash fragile wall terrains (like the Move Mountains spell).
