Allow machines to also act like a cable

[The4codeblocks]

currently machine and wire behaviors are mutually exclusive, such that the code assumes that there can't be both

This doesn't make sense from a realism point of view. I don't know about you, but I don't have my computer transferring power to my washing machine and fridge.

Maybe there could be a special case for certain machines, transferring power to more of the same machine (something like what #443 would need), but that could be implemented in the individual machine's code.

I don't mean it for the base mod to implement the behavior for every machine, I mean it to support it, for whatever other mods
