Multi item belts splitters Splitting and pass through

[KaliKatz]

On a multi item belt, splitters that are used to send an item to the left or right need an option to also allow that item to pass through. Only the item selected gets split while other item on same belt pass through.

This is performed by setting a filter on a splitter and then adding another splitter to split filtered items.
This change will not add anything new to the game and can be accomplished by existing tools.
Not gonna be even considered.
