[K12OSN] Broadcast message

[Luis Montes]

This can be done using xmessage. Since it is part of XFree86, we don't 
have to worry about which window manager is being used.

One thing I'm not sure about are permission settings with xauth. It also 
need to have the DISPLAY environmental variable temporarily set to the 
display you wish the message to pop up on.
