Firewall open port

[Tendoncs]

New to the Git Stuff I will have to figure out how to make a new branch and update code there. But I found this bug. The software does not close the port it opens when it stops the server.

I created a DeleteFirewallRule

    private Task DeleteFirewallRule()
    {
        return Task.Run(() =>
        {
            string cmd = RunCMD("netsh advfirewall firewall show rule \"Screen Task\"");
            if (cmd.StartsWith("\r\nNo rules match the specified criteria."))
            {
            }
            else
            {
                cmd = RunCMD("netsh advfirewall firewall delete rule name=\"Screen Task\"");
                Log("Screen Task Rule was removed from your firewall");
            }
        });
    }

Added a call to it in the btnStartServer.Tag check.

        if (btnStartServer.Tag.ToString() != "start")
        {
            btnStartServer.Tag = "start";
            btnStartServer.Text = "Start Server";
            isWorking = false;
            isTakingScreenshots = false;
            Log("Server Stoped.");
            //Added
            await DeleteFirewallRule();
            return;
        }

Also, added "Rule removed" to log window.

Also Added Remove Firewall rule to the application close

@Tendoncs a lot of users requires the port to stay open, but we can add an option to delete ports on exit.
