[XForms] Redone client callback

[Jeff]

I changed code on my client callbacK to match the other callback calls.
 In forms.h:
typedef int (*FL_CLIENT_CALLBACK)(struct forms_ *, void *);

and:

FL_EXPORT FL_CLIENT_CALLBACK fl_register_client_callback(
        FL_FORM *form,
        FL_CLIENT_CALLBACK rcb
        );

I added the new call in forms.c:
FL_CLIENT_CALLBACK
fl_register_client_callback(FL_FORM *form,FL_CLIENT_CALLBACK 
clientCallback){
  FL_CLIENT_CALLBACK old_rcb;

  old_rcb =form->client_callback;
  form->client_callback = clientCallback;
  return old_rcb;
}
