Subject: [PATCH] SoundPlayer: Add start_new_file() to VisualizationWidget's
 API

This adds a new start_new_file() function to VisualizationWidget which
is called when the player starts a new file, passing the filename of the
file. This allows VisualizationWidget subclasses to do any setup needed
when a new file is started.
