Implemented the various printf() functions under

Unicode with their GNU libc 2.2 funtions. This
    saves us some unicode<->ansi conversion and we
    no longer need the experimental printf() code
    in string.cpp. I had to implement wxSprintf()
    using wxSnprintf() as the former doesn't exist
    in Unicode GNU libc 2.2.
