Four new strings in gnome-icon-theme

[Christian Rose <menthos gnome org>]

Some missing files were added to POTFILES.in in the stable and string
frozen gnome-icon-theme HEAD branch, which results in four new strings
being available for translation. Please update your gnome-icon-theme
HEAD translations.

The person fixing it didn't notify translators (which regardless of
the change's nature would have been *very* welcome since we're both in
string freeze and code freeze, so unannounced changes aren't expected),
but here is your heads-up.
