The items in the list must be ToolboxItemContainer objects. If the toolbox implementation is organized in categories, this retrieves a combined list of all categories. The list must be read/write, as new items may be added to it.
If a category name is provided, only the items in that category should be returned. If no category is specified, all items should be returned.
