Use arena class "config names" in /ma autogenerate.

Swaps the weird "camel casing" approach in the autogenerate command out
with simply using the "config name" of the arena classes when creating
class selection signs.

This fixes the breaking change to how classes are resolved in a previous
commit, but only in future arena generation procedures. Arena generated
before this change may still contain broken class signs.
