[PATCH] Allow to rename .desktop file with empty name, update all used .desktop locales on rename

[Christian Neumair <cneumair gnome org>]

The attached patch ensures that we'll allow to rename .desktop files
with an empty name, and also updates the .desktop name for all locales
the user currently uses as he renames .desktp files.

I'm not sure whether we should apply renames to all languages,
gnome-ditem-edit is very similar to the proposed semantics, although it
just updates the first locale and "C".

The patch was compiled while tracking down
