[FEATURE] Human readable names for special folders

The names of some special folders (user upload,
temporary files, recycler) were historically
converted to a human readable string. This is partly
broken in the current version, especially the sorting
gets mixed up. This commit changes the concept to
make the mapping more flexible (i.e., the driver can
decide what folder has which special role) and also
fixes the name mapping and sorting.
