	@brief The PrefixConfigurationDialog class
	
	Shows the whole directory tree of the user elements collection, one
	text field per directory, filled with the prefix that directory
	already has in qet_labels.xml (empty when it has none, which means it
	inherits the prefix of its parent directory).
	
	Nothing is written while the dialog is open : validating calls
	QetLabelsFile::save(), cancelling leaves the file exactly as it was.
