Forthon text output going to terminal instead of notebook

[sballin]

When running Forthon code in a Jupyter notebook, if the print statements are in Fortran, their output appears in the terminal where jupyter was started, rather than in the notebook cell. When I create a "hello world" program using Cython, which translates python to C and creates a .so file that can be imported in python, the outputs appear in the notebook properly.
