RibbonWindow: Add windowStatus property.

1. RibbonWindow.Status.Stardard: Create new window instance whether it already has one or not.
2. RibbonWindow.Status.SingleTask: If it already has one instance, the current instance will be closed and a new one will be created.
2. RibbonWindow.Status.SingleInstance: If it already has one instance, the current instance will be activated, no new instance will be created.
