Subject: Destroy water walking boots on lava first.
X-Git-Tag: NetHack-3.6.0_RC01~684

Destroy water walking boots on lava first.

This avoids a player being left standing on lava if their boots are burned up and
they survive the damage.

This change is originally due to Steve Melenchuk, fixed up by Derrick Sund.
