Default to Console I/O

The default I/O units, specified by READ fmt, READ (UNIT=*), WRITE (UNIT=*), and PRINT fmt, should not be units 5 (input) and 6 (output), but, rather, unit numbers not normally available for use in statements such as OPEN and CLOSE.

Changing this would allow a program to connect units 5 and 6 to files via OPEN, but still use READ (UNIT=*) and PRINT to do I/O to the "console".

This change probably requires the libg77 project.
