  Summer's cleanup, a really big one:
  * AUTHORS: added William and Bjorn
  * include/libxml/*.h *.c README doc/*.html etc.: changed old email to
    daniel@veillard.com hopefully I won't have to do this again
  * doc/Makefile.am doc/html/*.html: cleanup makefile, checked that
    docs can be rebuilt cleanly now
  * include/libxml/xml*version.h*: removed include/libxml/xmlversion.h
    from CVs it's generated, added include/libxml/xmlwin32version.h
    also generated but which should change far less frequently.
  * catalog.c nanoftp.c: made sure to include libxml.h not
    libxml/xmlversion.h directly
  * include/libxml/*.h: include xmlwin32version.h instead of xmlversion.h
    when compiling on WIN32 and MSC
