While writing a new Task, I was wondering, why it didn't schedule immediatly after calling Start(). Turned out Start() wasn't even calling Task::StartTimer(...) to trigger / wake up the Scheduler. So this changes Task's Start() to call StartTimer(0) to immediatly trigger the Scheduler at the end of Start(), but Tasks can opt out of it, if they aren't ready yet (like Timers).
