Adds both SortableCategoryList as well as SubcategoryList. 

Both make use of sorting, which is disabled for now as it seems we don't have a sorting key anymore.

/**
* This list offers the option for the code to provide the developer
* with links to sort the given categories.
*
* NOTE: This UI currently does not scale well with large numbers of
* items since it just lists all of them. It would probably be nice
* to integrate a paginator as well to as to allow the user to move an
* item in large distances and to insert an item in the middle. Right
* now, when you add an item it is just placed at the end. However,
* if you want the item to appear in the middle then you must hit the
* "up" arrow n/2 times where n is the number of items in the list.
* This clearly is not a good setup.
