## About The Pull Request
See the title and the relative issue reports.
The logic here is that, if they can move, chances are they can also use
ladders (with a few exceptions such as camera mobs). This ought to
include both pAIs and lightgeists, even if they cannot directly interact
with about every other object in the game.
I have also moved lightgeists onto a new file, from colossus.dm.
## Why It's Good For The Game
This will fix#57061 and fix#69228.
## Changelog
🆑
fix: pAIs and lightgeists can now correctly climb ladders.
fix: fixed a small issue with the radial menu for ladders that caused
the user to travel down when abruptly closed.
