Vino: String changes.

[Chris Kühl <chrisk openismus com>]

There have been a few string changes to vino during the port to
GSettings. They are...

+ "If true, the server will listen to another port, instead of the
default (5900). The port must be specified in the 'alternative-port'
key."
+ "Listen on an alternative port"
+ "Lists the authentication methods with which remote users may access
the desktop. There are two possible authentication methods; \"vnc\"
causes the remote user to be prompted for a password (the password is
specified by the vnc-password key) before connecting and \"none\" which
allows any remote user to connect."
+ "The password which the remote user will be prompted for if the \"vnc
\" authentication method is used. The password specified by the key is
base64 encoded. The special value of 'keyring' (which is not valid
base64) means that the password is stored in the GNOME keyring."
+ "The port which the server will listen to if the
'use-alternative-port' key is set to true. Valid values are in the range
from 5000 to 50000."
