Adjusted several races to remove the "no magic reanimate flag" allowing you to raise them with necromantic magic, left dragons alone because in my test if you revive a dragon it becomes invisible.

Races changed:
Dragon Preist
Dwarven Centurion, Sphere, Spider
Flame, Frost, Storm Atronach
Horses
Ice Wraith
Skeletons
The Forge Master
Scrib

All other races you could already resurrect.
