Calling fgl_init4gl() initialization function

Four Js Business Development Suite (BDS) provided a few utility functions in the libfgl4js.42x library. This library had to be initialized with a call to fgl_init4js():
MAIN
   ...
  CALL fgl_init4js()
   ...
END MAIN

Genero Business Development Language still supports the fgl_init4js() function, but only for backward compatibility. Calling this function has no effect in Genero.
