We (Aldo & me) have thinking about how to differentiate a regular category
and a workspace category.
The option is to create a category container called "Workspaces" with
parentId 0 (the top)
The steps are:
1. Check the "WorkSpace" categId and list all categories with an equal
2. This "WorkSpace" category must be unique. If before creation exist a
category with the same name and parentId this one will be renamed.
3. For default tiki-browse_categories and tiki-admin_categories don't
show the "Workspaces" category and it's childs.
What do you think?
