I decided to add some functionality to the program so that it
will actually run unix + dos shell commands in the 'terminal'.
See:
http://seriss.com/people/erco/fltk/#SimpleTerminal
So you can run commands like ls/dir/ps and see predictable results
just like a normal terminal.
The widget of course does NOT handle programs like vi or emacs;
that would involve full on terminal emulation, which is beyond
the scope of this example.
But for simple application command prompts, this should give people
a very good starting point, if not a complete example.
Adding the shell command execution was just a few lines of popen()
code, which went a long way towards making this example very realistic.
Tested on linux and windows.
