Added SetReuseAddress() method to WebSocketServer

[jhovgaard]

By using SetReuseAddress() before Start() you don't have to wait for TIME_WAIT to timeout. Normally you will recieve the following exception if you try to start websocket-sharp on the same port within TIME_WAIT:

[SocketException (0x2740): Only one usage of each socket address (protocol/network address/port) is normally permitted]

It looks interesting.

But, isn't it better to add as a property?

...
    private bool                               _reuseAddress;
...
    /// <summary>
    /// Gets or sets a value indicating whether the server is allowed to be bound to an address
    /// that is already in use.
    /// </summary>
    /// <remarks>
    /// If you would like to resolve to wait for socket <c>TIME_WAIT</c>, you should set this
    /// property to <c>true</c>.
    /// </remarks>
    /// <value>
    /// <c>true</c> if the server is allowed to be bound to an address that is already in use;
    /// otherwise, <c>false</c>. The default value is <c>false</c>.
    /// </value>
    public bool ReuseAddress {
      get {
        return _reuseAddress;
      }

      set {
        if (!canSet ("ReuseAddress"))
          return;

        if (value ^ _reuseAddress) {
          _listener.Server.SetSocketOption (
            SocketOptionLevel.Socket, SocketOptionName.ReuseAddress, value);

          _reuseAddress = value;
        }
      }
    }
...

Could you test the above?

[jhovgaard]

I agree, better with property. It worked perfectly. Commited.

I will merge this PR, and then add the following comment to that .cs file.

Is it okay?

[jhovgaard]

Yes, that's cool :-)
