Ropes should be 'u'sed to transform a water or chasm tile into a rope-bridge-over-chasm/water tile; they should be interactable () to destroy them, and fire should burn them. Elven ropes should be the same, but creating a different tile type which can be uprooted by \ to reuse. Perhaps a rope bridge should be a grey/brown ~ symbol, but perhaps not.
