Add beach towels. (#31667)

* Add beach towels.

* Add basic towel. Attempt absorbency. Add towel names.

* Make towels pick up and spread blood.
Move towel place-on-floor function to beach towels.

* Move amount to base cleanable. Refine towel procs.

* Ensure towel picks up blood.

* Add species sprites and inhands.

* Apply suggestions from code review.

* Fix ussp space ruin.

* Whitespace.

* Prevent picking up blood DNA already on the towel from mobs/items without decal amounts.
