[ubuntu-art] [Breathe] Power option icons (help wanted)

[Cory K.]

I'm hoping we can get someone to take these 7 icons on. Should be fairly
strait-forward.

    * Shutdown
    * Reboot
    * Logoff
    * Suspend
    * Hibernate
    * Lock Screen
    * Switch User

Submissions should fit with what's currently being generated. Here's an
idea of what's currently in Oxygen:
