Annotations category: adding an annotation category information

As a Nuxeo Web UI user, when adding an annotation from the viewer, I can select a category so as to be able after to filter annotations for a given category later on. If I don't select any, by default, no category is added. I can select several categories if I want.
The selection component is displayed in the same area as the "status" one. 

They are then displayed like we usually display tags, with a little eclipse around.

Remarks: we display only the multi-select component with a tool type “Category”. Default categories are : Juridical, Branding, Marketing , Packaging.

Categories labels are translated, following global ARender display locale.
