* Now stores the URL of downloads in the DownloadProgressView and in the settings,

so that we can eventually restart downloads.
* Checks if a downloaded file already has a previous download and replaces it.
  (Actually, this should take the path into account, not only URL.)
* Stores the URL as "META:url" attribute, as the good old NetPositive did.
