New icons for gnome-logout dialog

[Josué Alcalde González]

I update Yasis icon theme some days ago.
It is GPL and its author is Silvestre Herrera.

I found a new gnome-session-logout icon, and it looks very good for me.
Based on this icon and others Yasis icons, I have designed some new
icons for the logout-dialog.
They aren't very polished, but they looks good for me.

I make a "fake" screenshot with the new icons.

I would like to hear your opinions.
