    Add SI and SO control codes

    SI and SO allows change the G0 and G1 selection. This implementation is not
    full vt100 compatible, but it is complatible with linux virtual terminal
    implementation. For full vt100 compatibility we need remake a lot of stuff
    relate to the different charmaps.
