Title: refactor script_task.rs fn handle_msgs for vertical alignment in 22 arms match

This vertical alignment greatly increases readability of this 22 arms match statement. To assess the readability I tried to read the first argument to the constructors in each pattern, e.g. `FireTimerMsg` in `FromScript(FireTimerMsg(FromWorker, _))`.
