Restore Networking Functionality

[Cheeseness]

Recently, @bobsayshilol became unable to host the custom matchmaking server we were using for the game. We've merged a commit ( #260 )that switches it back to the default Unity one, but it appears that another bug has crept in which is preventing networking from working properly.

@bobsayshilol Looking at the commit again, I'm wondering if maybe there aren't more things that would be in networkManager.cs like NAT handling and player caps that would require attention?

I would hazard a guess that it's this line https://github.com/Double-Fine-Game-Club/bad-golf-community-edition/blob/master/Assets/scripts/network/networkManager.cs#L165 causing the issue, and looking into it I don't think Unity provides a default Facilitator (the thing that enabled the NAT punch-through) so I guess the host would have to port forward to allow connections (port 11177).

Also if https://github.com/Double-Fine-Game-Club/bad-golf-community-edition/blob/master/Assets/scripts/network/networkManager.cs#L261 is hit it should probably stop you from hosting a server too, so that may be an issue.
