Subject: [PATCH] Replace ScriptRuntime#main(String scriptClassName, String[]
 args) by ScriptRuntime#main(Class scriptClass, String[] args) and to
 optimizer.Codegen#generateMain code to generate call to Class.forName before
 calling ScriptRuntime#main. In this way script byte code can access Class
 object if generated script is loaded via different class loader then Rhino
 classes.
