## About The Pull Request
I was debugging when I found that holding alt spams the UI with log
messages. The source UI causing this also wrote in old ES5 syntax . I
updated our linter to error when you write JS code like an ancient
scribe (circa 2009).
I also bumped some dependencies and fixed all the linter warnings in
tgui:lint.
The alt-click-drag functionality still works:
