Reported by me ;-} during beta testing last Fall, engulfers have a
tendency to re-engulf the hero immediately after expelling him/her.
Use mspec_used (set when expelling rather than engulfing) to make
them wait a turn or two. Initially that made the too-soon engulf
attacks always miss, so this changes too-soon engulf to a touch or
claw attack instead. Some tuning in damage or message may be needed.
