1.9.1: Initial Beta version

1.9.2: Fixed shebang in umenu.py to be /usr/bin/umenu.py

1.9.3: Fixed problem where running a background command 
        when UMENU2 run with -t failed to run the command.
        Fixed by adding os.setsid() to ufork.py, moving the
        ufork.py call from Commander.run_script() to
        Commander.make_script_line_array(), and adding
        os.sleep(1) near bottom of umenu.py loop, if
        cnf.cnf['term'].
