polymorphing into placeholder monsters

Browse Source 
"human", "dwarf", "elf", "gnome", and "orc" are all flagged M2_NOPOLY;
so is "giant".  But dwarf and gnome are ordinary monsters and should
be eligible to be polymorph targets, so take the no-poly flag off of
them.  The others are used for corpses and not intended to be distinct
monsters.  But they are reasonable polymorph targets, so if player
with control picks any of them, choose a substitute.  The exception is
human, which already has special poly-self handling.
