Translation for ubuntu specific strings in system-tools-backends

[Jorge Bernal]

I've updated the Spanish translation with the two new strings. Available at:
http://amedias.org/~koke/patches/ubuntu_system-tools-backends-es-update_0.patch

I've made it with cdbs-edit-patch with a 99 priority.

Apart from this, I think this is not the best method to maintain the 
translations. Do you have any better idea?
