Fixes#111
Casting stone-to-flesh at a random statue animates it as a monster
(created via direct call to makemon()) at an adjacent or nearby spot
if there is already a monster at the statue's spot, but doing so on
a statue of a petrified monster (create attempt via montraits() which
called makemon() without the ADJACENTOK flag) turned it into a corpse
instead. Pass an extra argument to montraits() so that it behaves
the same normal statue animation for stone-to-flesh without changing
how it behaves when reviving corpses for undead-turning.
