modules/visualization/visual/visual.c: strings review.

 to give it a try (QT is the default method).
  + Known issues: no fullscreen yet, memory leaks, ugly code, ...
  + Known goodies: it's a few % faster than QT here (playing a DVD). If
      experienced OpenGL and Altivec programmers could have a look and
      give some advice, I guess the performance increase might become
      noticeable.

* modules/mux/mp4.c: fixed recent screw-up in movie duration.

* modules/gui/gtk/preferences.c: don't rely on module definitions having an add_category_hint().

still some  printfs in dvbsub.c. Would  need to spend some  time reading
the code to remove them.

* modules/gui/wxwindows/interface.cpp: removed unused strings.
