[css-print][meta] css-print left unnumbered

[frivoal]

Despite the great numbering, css-print's directory is still unnumbered.

Simple oversight, or was there some reason to leave it out?

It's not a module and will never be updated; I also left css-mobile and similar alone.

Ah, oops. I mistook it for css-page. Makes sense now.
