	* gui/dialogs/select-source-dialog.[ch]: new dialog for allowing the
	user to select a source.

	* gui/dialogs/copy-source-dialog.c (copy_source_dialog): use the
	select_source_dialog function to ask user for the source to use.
	(source_selected_cb): removed unneeded function.

	* gui/dialogs/Makefile.am: added new files.
