update gnome shell extension: replace dbus code by gio

[Le Gluon du Net <legluondunet free fr>]

Hello 

I'm trying to update some Gnome shell extensions to work with 3.8 version.

for gnome-shell 3.4, dbus is obsolete and replace with Gio.

Could you help me to update this part of code?

--------------------------------------------------------
/* Zeitgeist D-Bus Interface */

const LOG_NAME = 'org.gnome.zeitgeist.Engine';
const LOG_PATH = '/org/gnome/zeitgeist/log/activity';
const LogIface = {
    name: 'org.gnome.zeitgeist.Log',
    methods: [
        { name: 'GetEvents',
          inSignature: 'au',
          outSignature: 'a'+SIG_EVENT },
        { name: 'FindRelatedUris',
          inSignature: 'au',
          outSignature: '(xx)a(' + SIG_EVENT + ')a'+ SIG_EVENT + 'uuu' },
        { name: 'FindEventIds',
          inSignature: '(xx)a' + SIG_EVENT + 'uuu',
          outSignature: 'au' },
        { name: 'FindEvents',
          inSignature: '(xx)a' + SIG_EVENT + 'uuu',
          outSignature: 'a' + SIG_EVENT },
        { name: 'InsertEvents',
          inSignature: 'a' + SIG_EVENT,
          outSignature: 'au' },
        { name: 'DeleteEvents',
          inSignature: 'au',
          outSignature: '(xx)' },
        { name: 'DeleteLog',
          inSignature: '',
          outSignature: '' },
        { name: 'Quit',
          inSignature: '',
          outSignature: '' },
        // FIXME: Add missing DBus Methods
        // - InstallMonitor
        // - RemoveMonitor
    ],
    properties: [
        { name: 'Get',
          inSignature: 'ss',
          outSignature: 'v',
          access: 'read' },
        { name: 'Set',
          inSignature: 'ssv',
          outSignature: '',
          access: 'read' },
        { name: 'GetAll',
          inSignature: 's',
          outSignature: 'a{sv}',
          access: 'read' },
    ]
};

const Log = DBus.makeProxyClass(LogIface);
const _log = new Log(DBus.session, LOG_NAME, LOG_PATH);

--------------------------------------------------------

I tried to replace the last 2 lines by:

const Log = Gio.DBusProxy.makeProxyWrapper(LogIface);
const _log = new Log(Gio.DBus.session, LOG_NAME, LOG_PATH);

with no success...

Thank you for your help.

LGDN.
