Plugin network interface selection should track olad unless you've explicitly overridden them. #1466
Description
When you use the -i option on olad to specify an interface, all the plugins should follow this too unless they specifically have ip = eth0 type lines in their config files. Currently olad's webserver binds to -i, but everything else defaults to the first interface found.
