#1 need a way to re-scan a host's interfaces

[JofCore]

I need a button or something to re-scan a host/router
and update the interfaces accordingly... currently, if
a router's interfaces change, there's not an easy way
to edit them or update them to the current status on
the router.

I'm thinking I'll have a button or something on the
host configure page that will sync the interfaces to
the live router config or something..
