* Implementation of RenameVolumeDialog.
*
* Show a tree with possible volumes and sub-volumes, and ask the user to
* enter the desired name (or volume number).
*
* We need to have the tree, rather than just clicking on an entry in the file
* list, because we want to be able to change names and volume numbers on
* disks with no files.
