New Windows utility function: is_console_handle().

Browse Source 
Rather like isatty() on Unix, this tells you if a raw Windows HANDLE
points at a console or not. Useful to know if your standard output or
standard error is going to be shown to a user, or redirected to
something that will make automated use of it.
