units: changing undead representations of some

Scorpions: use spider, better than the humanoid
Wyverns: are a rather drakish species than gryphonic
Falcons: more of a huge bird than a tiny bat

Sand Scuttler: official name for the unit is now Scorpion, as
having both the variation and unit name being the same would
show the same name twice.

Lighter and with less powerful talons than other raptors, falcons instead favor the use of their beak to kill their targets. Their keen eye and capacity for domestication makes them a populous and well-known creature, used both by nobles in sport, and by nomads or tribes who find them useful in hunting for food. Falcons occasionally find a role on the field of war as well, with certain falconers training their birds to distinguish between friend and foe, making them a useful asset to aid in an army’s charge."
