Gives the automated IV an output pipe and lets you rotate it (#94058)

## About The Pull Request

Plumbing IV drip now has an input and an output, the input only works
when it's injecting and the output only works when it's draining.
You can rotate with it alt click like all other plumbing things now, IV
drip hotkeys removed

## Why It's Good For The Game

It's an *automated* IV drip, the whole point is you can connect it to
plumbing and having half it's functionality just not work is bad.
As for the rotation it's waaaaaay more useful than the IV hotkeys for
plumbing.

## Changelog
