PATCH - Add DnD files onto archiver files with help of file-roller

["Nelson Benítez León" <nbenitezl gmail com>]

Hi, I would like to have this feature in nautilus, it's in winxp explorer and I like it, you can easily drop files onto a zip or other archiver files, and they get added to the archive.. it's very handy and it's possible thanks to file-roller. Hope you try the feature and enjoy it!.

See http://bugzilla.gnome.org/show_bug.cgi?id=377157  for more info.
