[Optimization] Optimise GetClosestPlayer

[AlexMog]

The method GetClosestPlayer seems to be used on Update behaviours, and is a bruteforce way to check which player is the closest.
Better ways should be used to avoid checking all players.

Decompiled code (Class: Player):

public static Player GetClosestPlayer(Vector3 point, float maxRange)
{
	Player result = null;
	float num = 999999f;
	foreach (Player player in m_players)
	{
		float num2 = Vector3.Distance(player.transform.position, point);
		if (num2 < num && num2 < maxRange)
		{
			num = num2;
			result = player;
		}
	}
	return result;
}

In same class:

public static void MessageAllInRange(Vector3 point, float range, MessageHud.MessageType type, string msg, Sprite icon = null)
	{
		foreach (Player player in m_players)
		{
			if (Vector3.Distance(player.transform.position, point) < range)
			{
				player.Message(type, msg, 0, icon);
			}
		}
	}
