Add PrivData() field to wxPrintData since MSW's printer

sometimes seem to save data in an extra field. The
    original author of the patch chose to save it in char*
    so I kept that, although void* would probably be correct.
    The patch is against 2.4.2 and the code has been reshuffled
    since then so that the patch had to be redone entirely.
