Cas Editor: group annotation types by namespace?

[Jens Grivolla]

Hi,

I was wondering if it wouldn't be more useful to group annotation types 
in the "mode" and similar menus by namespace rather than inheritance.

I don't think most users care much about supertypes, and mostly don't 
know about them, whereas the namespace seems to me to be a more natural 
way to organize the menus.

I think a flat top level with all used namespaces would work quite well, 
and the submenu with the annotation type names would not need to include 
the prefix.  What do you think?
