#2 Create nested classes for AppSettings keys that contain dots

[WebGear Ltd]

E.g. if appSettings has:
"Smtp.Host"
"Smtp.Port"
"Smtp.Sender"

then the output should be something like

public static class Config {
public static class Smtp {
public string Host;
public int Port;
public string Sender;
}
}

so it can be access like Config.Smtp.Host
