git issue #994 - killed by a touch of death

Issue reported by vultur-cadens:  cause of death reason for touch
of death and death due to loss of strength only showed the cause,
not the monster spellcaster who was responsible.

This changes
|Killed by a touch of death.
to
|Killed by the touch of death inflicted by the Wizard of Yendor.
and
|Killed by terminal fraility.
to
|Killed by strength loss inflicted by a chameleon imitating an arch-lich.
(The 'imitating' part doesn't fit on the tombstone but will be present
in logfile/xlogfile.)

Noticed while implemented this:  touch of death was modifying u.uhpmax
and basing death vs damage on that even when hero was polymorphed.
It now rehumanizes the hero in that situation.

Closes #994
