[ubuntu-art] Please merge humanlist

[Étienne Bersac]

Hi,

Congratulation for the new theme ! Wallpaper and gdm theme are very
nice. I updated HumanList, branching ubuntu-gdm-themes. The "code" is at
https://code.edge.launchpad.net/~bersace/ubuntu-gdm-themes/humanlist .

I updated images and tweaked the xml to fit well with the new theme.
Needs to update the screenshot, but i'm stuck with bigsized
Xnest/Xephyr :(

Regards,
Étienne.
