Ignore loop and docker network interfaces?

Currently, virtual network interfaces are included in the total values calculated in the network widget (besides VPN interfaces which have been removed) but I feel like maybe we should just include physical network interfaces like ethernet and wifi.

I believe what should be done instead is #20

So #20 has been implemented, but it only allows for specifying one interface. #148 has been opened which would allow for specifying a list of interfaces.

So I think the question comes down to what the default should be:

• Should we only show physical network interfaces by default and require users to opt into showing virtual interfaces too once Allow specifying multiple network interfaces #148 is implemented?
• Or should we show all interfaces by default (vpn interface too?) and require users to opt out of virtual interfaces?

It might be good to have an option specifically for this. I'd also like to allow for specifying network interfaces to not show: #149.
