Build-able Conveyor Belts and Configurable Y Junction Pipes

[Sundance]

I did query this on the Discord and someone mentioned that conveyor belts are "Code Hell". I'm sure if that wasn't true we'd already be able to build them.

Odd. There's this weird admin spawn item called an engineer in a box that does exactly this - it spawns conveyor belts. I can't recall now if these belts are actually togglable (word pending in oxford dictionary) but the ability to make them is there.
Aside from this, other servers can build conveyor belts no issue. An example I'd see when lurking on r/SS13 is a food conveyor, which always looks fun. Or a prison threadmill which causes prisoners to constantly run...with cuffs on. Not so fun but hey, innovation in SS13 is rarely moral.

The Y pipe seems like good fun. It.. exists in a certain capacity AFAIK - the loafer has a filter function whether the person going in is alive/human and will spit it back into a separate pipe if true.
