feat: Use Steam API to detect Query and game ports

[dgibbs64]

What is this feature about?
It is possible to use the steam API to get info about game and query ports. This could allow valve queries to check and confirm the query port without requiring port guessing. See below for an example. Gamedig could do a lookup against the api and match a query port then use that information to quickly and accurately query the correct port

But what if there are several servers on the same IP, which server would the query be made on.

Would this be useful if you are querying multiple servers? #444. Like searching for IP in the Steam API and querying each port returned.

[dgibbs64]

when you are querying you will always be using ip:port. A lookup on the gameport is used to find a match.

This would be used only when using a port for querying?
So if you query only using an IP, skip the Steam API detection?

[dgibbs64]

You would need to know at least the query or game port as an ip could have multiple game servers
