consoles: Allow adding and editing VNC
- The "Console" card is always present and let's people manage VNC server settings while the machine is off. - The "VNC console" tab is always present when the machine is running and let's people add VNC. - There is no way yet to change VNC server settings for a running machine since there is no good place for the button that would open the dialog.
