[plasma-mobile] applications/webbrowser/src: Nepomuk magic for downloading files

[Sebastian Kügler]

Git commit 38861fb962d889ae5e654e619161f68ba36f1b3f by Sebastian Kügler.

Nepomuk magic for downloading files

With this patch, the browser
- adds downloaded files to Nepomuk,
- tags them as "Download" (not translated -- maybe we should do that?),
- and adds them to the current Activity, as Ivan described and
- adds the source URL of the file as comment to the downloaded file's
  metadata

Ivan, could you check that the activity part works?
