fix SC343-9, bones handling for corpse/statue of unique monster (trunk only)

The logic in cant_revive() was a little off, so reviving a unique
corpse or statue on a bones level would recreate that unique monster instead
of making a doppelganger who's imitating it.  Fixing that was simple but had
the unintended side-effect of making it impossible to deliberately create
unique monsters with ^G in wizard mode.  So create_particular() has been
modified to let the user override the zombie or doppelganger conversion.
And then when not overriding, shapechangers took on random appearance, so
this also changes create_particular() to override shape changing.  And that
has the side-effect of making chameleons or vampires start out as themselves
instead of as random critters or bats/fog clouds.  [Better stop now! :-]

    resetobjs() also needed to have extra corpse handling when saving bones
because the fix for revival wouldn't prevent you from turning to stone by
eating apparent-Medusa's corpse.  Statues of uniques and corpses of special
humans like vault guards and shopkeepers didn't need anything extra; they
can retain original form until an attempt at revival is tried.

    I'm not going to try to adapt this for 3.4.4.
