Fix library thumbs, decouple save/bookmark, smaller dot + yellow star

- Skip video files in library thumbnail generation (PIL can't open them)
- _on_bookmark_done only sets bookmarked for bookmark ops, saved for save ops
- Smaller green dot with yellow star to its right
- Default bookmark star color: yellow (#ffcc00)
