Subject: [PATCH] Fix save problems on shutdown
- Save level.dat first, in case the shutdown is killed later
- Force run minecraftserver tasks and the chunk source tasks
while waiting for the chunk system to empty, as there's simply
too much trash that could prevent them from executing during
the chunk source tick (i.e "time left in tick" logic).
- Set forceTicks to true, so that player packets are always
processed so that the main process queue can be drained
