Adds a Duplicate feature to Dolphin, showing up as a menu item in the File menu that appears when one or more items are selected and the directory is writable. Duplicated items receive the names of the original files with " copy" appended before the file extension, if any. If only one item was duplicated, a rename operation is immediately initiated on it, allowing the user to choose a new name.
