Option to display Knowledge Base widget (without live chat) during offline hours

Option to only show help centre from chat widget. Especially useful when chat is 'offline'.

When offline hours are enabled, the widget is completely hidden from the site. This also hides the knowledge base, which seems like a strange thing to do. The whole point of the knowledge base is to find the answer yourself. Hiding the whole widget when chat isn’t available means the customer can't even try to find the answer themselves.
