patch: add information about the icon to gvfs-info

[Richard Hughes <hughsient gmail com>]

Whilst debugging an icon theme bug, I wanted to know what icon would be
chosen for a file. It turns out gvfs-info gets all the properties and
prints them, but for an icon prints:

  standard::icon: GThemedIcon:0x8df7200

This isn't very helpful :-)

Patch attached makes it something like this:

  standard::icon: (fallbacks:false)
   1. name:package-x-generic
   2. name:application-x-servicepack
   3. name:gnome-mime-application-x-servicepack
   4. name:application-x-generic
   5. name:text-x-generic

Comment welcome. Thanks.

Richard.
