Subject: [PATCH] SparklyPaper: Reset dirty flag when loading maps from the
 disk

Original project: https://github.com/SparklyPower/SparklyPaper

Patch description:

By default, the server will start rewriting all map datas to the disk after loading it, even if the map didn't have any changes
This also slows down world saving a lot if you have a lot of maps
