 // A regular DownloadItem (created for a download in this session of the
 // browser) normally goes through the following states:
 //      * Created (when download starts)
 //      * Destination filename determined
 //      * Entered into the history database.
 //      * Made visible in the download shelf.
 //      * All the data is saved.  Note that the actual data download occurs
 //        in parallel with the above steps, but until those steps are
 //        complete, the state of the data save will be ignored.
