-- can_remove(pos,node,stack,dir) returns true if an item can be removed from that stack on that node
-- can_remove(pos,node,stack,dir) returns the maximum number of items of that stack that can be removed
-- remove_items(pos,node,stack,dir,count) removes count items and returns them
-- both optional w/ sensible defaults and fallback to normal allow_* function
