Fix multiple dedicated servers running on same IP Address not working properly

[evilfactory]

This PR fixes two bugs:

1. Multiple servers on same IP wouldn't show up on the server browser, this is fixed by adding the port value check that was left out here: https://github.com/Regalis11/Barotrauma/blob/master/Barotrauma/BarotraumaClient/ClientSource/Screens/ServerListScreen.cs#L1766-L1767

2. Multiple servers on same IP would have "?" as ping, this is fixed by changing activePings so it uses a ServerInfo object instead of a string IP Address

This won't work, every single player would need to use that custom build of the game, and that's not doable.

I see the change is client side, never mind.
