Tested this by bringing different combinations of interfaces up or down.

It appears to be working. If I get one IP address from an interface, then bring that interface down and restart MapTool, I get a different address. Complete verification is hampered by the bug I mentioned in the sister issue, but things appear to be in order for this issue.

An edge case is what happens with all interfaces down. In that case no local address is displayed, not even a loopback, while on 1.13.2 and earlier a loopback would be shown. I wonder if we should still allow lookbacks to be shown in this case? It's certainly very niche, though there are folks who run multiple MT instances on a single PC and may be still benefit from being shown a lookback address.
