Added new global flag variable Py_InteractiveFlag and new function Py_FdIsInteractive(). The flag is supposed to be set by the -i command line option. The function is supposed to be called instead of isatty(). This is used for Lee Busby's wish #1, to have an option that pretends stdin is interactive even when it really isn't.
