While in theory both VNC and SPICE can be enabled at the same time, this is not expected to be common. Thus, rather than adding a 'SPICE console' tab, this renames the existing 'VNC console' tab to simply be 'Console'. This tab is setup to prefer exposing a VNC console, but if that is not enabled, then expose the SPICE console. The reason for this order is that the noVNC widget has had much more testing than the current spice-html5 widget. Thus if both VNC & SPICE are enabled, VNC is likely a more reliable choice at this point in time.
