(Re)-implemented speaker list sorted by ips

I'm not sure if it was lost, or deliberately removed, but I'm pretty sure I added this at some point.

This change quite simply sorts the speaker list by IPs, which will ensure that the list always come out in the same order.

I know that for most things we are working towards not depending on IPs, but as long as we still show them in the list, I still think it makes sense to sort by them.

What do you guys think?
