* modules/audio_output/input.c: created variables to allow for a autogenerated

  Visualizations menu (is this the right location?)
  Problems currently are: Doesn't work on the fly. where to start?
  For that reason it now also uses config options instead of variables.
* modules/visualization/visual/visual.c: small adaptions
* modules/gui/macosx/controls.m: fix warnings.
