IntervalTimer and TimeoutTimer use RAII, and can be used to replace all the time-based timeouts, lag-detection, "execute every N" we have. As it uses RAII, you can safely use it as static variable, class member, temporary variable, etc. As soon as it goes out-of-scope, it will be safely removed. This allows for much easier to read code when it comes to intervals.
