[PATCH v2 0/2] MR2808: Draft: SNI tray implementation

[Cherser-s (＠Cherser-s)]

Adds the tray icons implementation based on org.kde.StatusNotifierItem interface usage. Does allow restarting StatusNotifierWatcher object, but will fallback to XEMBED or internal tray, if wine gets initialized when there is no StatusNotifierWatcher object registered.
