* dejavu-fonts/DejaVuSansExtraLight.sfd: changed family name from
"DejaVu Sans" to "DejaVu Sans Light" (in case we add a Light weight
variant), so legacy apps that understand only 4 styles are happy.
* added Name ID 16, aka preferred family name, and Name ID 17, aka
preferred style name, so contemporary apps that understand more that 4
styles can use big fonts families "DejaVu Sans" and "DejaVu Serif". For
those, Extralight and Condensed are just styles not different families.
