String freeze break request for Vino

[Jonh Wendell <jwendell gnome org>]

In order to fix bug 330691 [1], a new string is mandatory:
"Others can access your computer using the address %s or %s."

The good news is that it's just a variation of another string that already exists:
"Others can access your computer using the address %s"

Summary: Currently we show the IP address of the machine. With the append of the string "or %s" we show the avahi hostname as well.
