OK, so this may be fairly trivial and such, but I always thought, in the
spirit of nethack, being able to do strange things: something dipped into
a potion of acid should damage the item.

Going with that, I wrote and tested a small patch to do just that. Right
now, it will rot/corrode anything rottable or corrodeable dipped into
acid. Some restrictions may be nice, but I didn't put any in (ie put keys
in acid, they'll corrode, though that doesn't accomplish anything. Plus I
could extend this to destroy items, but don't at this time). Rust/rot
proof things are not affected.

As usual, comments/feedback are welcome, email is good, I'll try to catch
things on rgrn.

patch (just simple diff, as I don't know how to make "real" patches)
