Steamworks P2P Integration

[cschoenig]

Integrating Steamworks.NET to make use of Steams Peer2Peer networking, Lobby systems, and matchmaking systems. With Steam's matchmaking:

• MasterServer is no longer necessary via public/private lobby searches
• NatHolePunch is no longer necessary via Steams relay servers for users who cannot direct connect.

In order to connect to a user all we need is their Steam ID or the ID to the lobby they are hosting.

public void ConnectToLobby(CSteamID lobbyId)
{
SteamP2PClient client = new SteamP2PClient();
client.Connect(lobbyId);
networkManager.Initialize(client );
}

Hosting a lobby requires your Steam ID, the type of lobby you want to create, and optionally a delegate for further actions (like updating lobby metadata) once it has been registered.

public void HostNewLobby(bool isPrivate)
{
SteamP2PServer myLobby = new SteamP2PServer(5); //Max connections
myLobby.Host(SteamManager.Me, isPrivate ? ELobbyType.k_ELobbyTypeFriendsOnly : ELobbyType.k_ELobbyTypePublic);
}

A list of active lobbies can be retrieved via SteamMatchmaking:RequestLobbyList()

UDP classes have been cloned and modified to their SteamP2P variants.
UDP still left intact as SteamP2P is merely an alternative for Steam applications and not a replacement of current implementations.

This is tested and working for up to 2 players. I have been having issues with 3 or more devices being connected (Mainly with NetworkBehaviors and NetworkObjects not being paired correctly).

There are conflicts because of the merges from a couple other PRs, it is probably just some code shifting. Do you mind resolving the merge conflicts. We will get to resolving the conflicts ourselves otherwise, just want to make sure they are working with your requirements after the resolve
