[Bug] - Upon creating a new "creature_template", unit_class is blank.

[TheSCREWEDSoftware]

While keira allows you to not choose any unit_class this will default to 0. Which the core automatically will set 0 to the next aviaible value which is 1 (i think is what i understood by the message). So it should at least in keira upon creating a new creature show the 1 - warrior class. this is the rror you get has invalid unit_class (0) in creature_template. Set to 1 (UNIT_CLASS_WARRIOR)
