Update to nucleo-0.7.1.  The list of changes is fairly verbose and I do
not have time to include it here (see ChangeLog).

Significant pkgsrc-related changes:

- ffmpeg plugin now builds (see new SUBST_* declarations).  Use
  ffmpeg-devel instead of ffmpeg.
- DESTDIR support
- GNU TLS option (enabled by default, evidently used by XML parser (?))
- Include graphics/gd, as its dependencies completely overlap and it
  doesn't take too long to build.
- Add x11/libXi to get Xinput functionality.
- Yet another header patch (patch-am)
- TODO file (place reading it on your TODO list today!)

Next up:  wm/metisse!
