WorldIMPLItemMoves.cpp: Maximum throwing range does not apply to containers

[estralis]

Items beyond weight 99 cannot be thrown over more than two tiles from a showcase to the map or from map to map.

However, containers (e.g. bags, item 97, weight 100) can be thrown from map to map over ten tiles. This is not intended. Potentially, containers are treated incorrectly, example of a line with an exception for containers:

Note that the maximum throwing range of two tiles works for showcase to map for containers.
