Eronarn's profane servitors and antihaloes

Profane servitor: An angel twisted into an undead monster by
Yredelemnul. He gifts these as a new tier above bone dragons. They are
in Yred's elemental colors, generated wielding a demon whip, probably
slightly better than a bone dragon in melee, and have res holy instead
of holy vuln like most undead. It also generates an umbra. Only Yred
gifts spawn them currently though they'd be great for some vaults.

umbra: An 'antihalo' composed of flickering darkness, which is the
opposite of a halo. Creatures in an umbra are harder to hit with both
ranged/melee, but get a stealth bonus. Currently only profane servitors
generate an umbra. Demons, undead, and worshipers of Yredelemnul
(at **+ for players, but all monsters) aren't harmed by an umbra but
still get the stealth boost.

The patch also changes the "Glow" status light to "Contam", and displays
"Glow" when actually backlit (for whatever reason: halo, sticky flame,
corona).
