Kurt eb7ed44b29 Finish splitting gen1/2 encounter types from parent class
Results in a little more code, but each path is less tangled
simplify some expressions
remove RBDragonair content in favor of a strict filter for catch rate

Move gen1 trade trainer names to stringconverter, since pk1/pk2 shouldn't refer to legality classes
