* ./src/playlist/playlist.c: lots of playlist behaviour enhancements.
* ./src/misc/objects.c: we do not hang on attempt to destroy an object with a non-zero reference count, but we still complain. * ./plugins/gtk/gtk_control.c, plugins/gtk/gtk_playlist.c: most controls such as play, pause, stop, next, fast etc. work again. * ./plugins/gtk/gnome_*: got rid of lots of useless wrappers which were a workaround for a bug in Glade. Instead, bootstrap.sh does the Glade fixes. * ./plugins/ffmpeg/ffmpeg.c: if there is already a video output with the appropriate properties, we use it.
