Spottedleaf da9d110d5b Remove chunk save reattempt patch
This patch does not appear to be doing anything useful, and may
hide errors.

Currently, the save logic does not run through this path either
so it did not do anything.

Additionally, properly implement support for handling
RegionFileSizeException in Moonrise.

Subject: [PATCH] Add Wandering Trader spawn rate config options
Adds config options for modifying the spawn rates of Wandering Traders.
These values are all easy to understand and configure after a quick read of this
page on the Minecraft wiki: https://minecraft.wiki/wiki/Wandering_Trader#Spawning
Usages of the vanilla WanderingTraderSpawnDelay and WanderingTraderSpawnChance values
in IWorldServerData are removed as they were only used in certain places, with hardcoded
values used in other places.
