MY MISTAKE (read below posts),
THIS PLUGIN DO ALMOST THE SAME THING AS AN INTERNAL Playback->Resume playback after restart SETTING
It is a general purpose plugin, which remember the last played song and can continue playing after restart.
homepage: http://sourceforge.net/projects/fooautoplay
installation: Copy foo_autoplay.dll into "foobar2000_dir/components", then enable plugin in Playback option.
