* Preserve old flush on save flag for reliable regionfiles

Originally this patch was in paper

* Fix some issues with the death event

- Entities potentially entering a glitched state to the client where
they appear to be falling over
- Donkeys losing their chest if the event was cancelled (only an
issue since the upstream merge)
- Some wither death logic running for an entity killed by a wither
