Made a zenity module based of the update-runescape-client script fork from Fallen Unia
This module should make it possible for other parts of the client to easily use zenity too.

added them in a comment below the fallback parameters incase someone needs them
Updated the update script to support zenity if it is installed.
otherwise it will fall back to xterm
