Gets version of currently running Zeitgeist daemon.
This method will return the version of Zeitgeist daemon this instance is connected to. If you call this method right after zeitgeist_log_new(), only zeros will be returned, a valid version number will only be returned once this instance successfully connected to the Zeitgeist daemon - ie. the value of the "is-connected" property must be TRUE (you can connect to the "notify::is-connected" signal otherwise).
