[BUGFIX] Allow folder sorting by modification time

The LocalDriver did not allow sorting folders by modification time.
However, the property is available and can be used for sorting (for
example in the file list). This has been adjusted so sorting by
modification time is possible for both files and folders and the file
list no longer displays folders in seemingly random order.
