Subject: [PATCH] Shuttle engines screentips and better examine (#78255)

## About The Pull Request

Shuttle engines now tell you how to install them based on what tool is
necessary to progress to the next step.
This information is included in the examine text of the engine, as well
as giving proper screentips when holding the correct tools.

## Why It's Good For The Game

Improves visual clarity on otherwise VERY hard to determine information.
The installation steps for the engine are literally nowhere in the game
so you are required to code dive to find out.

## Changelog

qol: Shuttle engines now tell you how to install them in their
screentips and their examine text.
