wet towel tweaks

When hitting with a wielded wet towel, use "you lash <mon>" like
bullwhip.  If you continue with the towel after it has dried out,
message reverts to ordinary "you hit <mon>".

Enhance damage slightly and double the wetness bonus when target
is an iron golem.  Damage was (tmp=rnd(1..7), max(tmp,6)); now it's
rnd(1 + 1..7) for other monsters, rnd(1 + 2*(1..7)) for iron golem,
with no cap of 6 for either.

Sequencing:  defer "your towel dries" until after the lash message.
