Ashen 16x Tough As Nails addon

Just a quick addon I made to bring Tough as Nails closer to the Ashen 16x aesthetic.

I haven't retextured the entire mod because a good chunk of the default TaN items already look pretty decent alongside Ashen. I mainly focused on tweaking the things that stood out the most.

Features:

Adjusted the colors of the flasks/canteens to match their actual materials.

Tweaked the leaf and wool armor to blend perfectly with the Ashen 16x vibe.

Minor updates to the UI to keep everything consistent.
