Neither belts nor splitters use power why should loaders do so?

Well two reasons:
1 - Inserters do use power, and these guys take their place. As it is now you can load and unload chests away from any power source. Which is normally impossible.
2 - The loaders can interact with chests, trains or ...

Just downloaded the mod and this makes my day :D

I also have a request, can you make them use power? (something like yellow:100kw red:200kw blue:400kw)
It sorta feels weird they don't use any. (if possible, you could make it a setting in the mod options)

Whether you do or don't thank you for this ...
