Default Client Auto-drink should pull from toolbelt

[Sevenless]

Swapping belts via wardrobe completely unbinding all your waterskins is a bit annoying. Might be some weird trick to make it work, but it's not intuitive to me at least.

Why not let the auto-drink pull from any liquid container in your toolbelt? Seems very intuitive to me, and makes wardrobes even better.
