Support black'n'white annotation colors

Support using of the black'n'white ornaments instead of the annotations colors. Consider two ways of implementations and choose one of them:
1) The ornaments are as usual colors (but ornaments). So, users can choose a ornament for one kind of annotations and a color for another one simultaneously.
2) The black'n'white ornaments are a separate mode of annotations coloring.

The decision should be based on the investigation of this feature in other tools.
