More or less applied patch by anxiety that implements showing a file

icon in the MediaPlayer Info window. I changed it a bit, so that the
icon retrieval only happens at the file change notification (quite
important, since the info window receives playback position notifications).
I also changed it to take the icon from the file first, if there is one.
Thanks!
