MethodGen

Hi!

When creating a MethodGen using the
  MethodGen(Method m, java.lang.String class_name, ConstantPoolGen cp) 
constructor, the getArgumentNames()  method always returns dummy names (arg0, 
arg1 ...).

I don't understand the comment in line 169, which may give a reason for not 
setting the argument names:
/* may be overridden anyway */

The following patch is not very nice, but seems to work (Probably adding 
methods getArgumentNames/Types to Method is a better approach?).
