fix injects loading old saves can't find state

[Die4Ever]

right now when you use injects on a class with states, it breaks old saved games because loading a game looks for the active state by the same class name instead of properly using inheritance like new games do

we can either

• copy all the states to the new class
• copy just the root code of the states into the new class and leaving the functions behind since they should inherit properly
• any other ideas?
