The liveCD safe graphics items are now translatable

[Sebastien Bacher]

Hey translators,

The liveCD items for 'safe graphics mode' were added previous cycle but
not added to the template, that has been fixed now and the strings are
now translatable in launchpad

(replace 'fr' by your locale)

Cheers,
