Aikar d231cef8cd Incremental Auto Save Players
Take same approach we did for chunks, and only save player if its been X time since last save,
instead of doing it all in 1 tick.

This is even more helpful considering Player Saving is done sync for File IO.

Subject: [PATCH] Auto Save Improvements
Makes Auto Save Rate setting configurable per-world. If the auto save rate is left -1, the global bukkit.yml value will be used.
Process auto save every tick instead of once per auto tick interval, so that chunk saves will distribute over many ticks instead of all at once.
Re-introduce a cap per tick for auto save (Spigot disabled the vanilla cap) and make it configurable.
Adds incremental player auto saving too
