Settings, marker and player information is not updated

[lmichaelis]

Hey there, we're trying out Pl3xMap on our server atm and I've noticed something strange: The plugin fails to update player and marker data as well as the world settings. After some digging I found the cause:

https://github.com/NeumimTo/Pl3xMap/blob/708cd08e1efe1b596f3cbc65fe9fcb909f749e0e/plugin/src/main/java/net/pl3x/map/plugin/util/FileUtil.java#L160-L168

For some reason the Runnable given to ForkJoinPool.execute is never actually run. I suspect that is is due to other plugins using the same pool an somehow blocking it. I don't know which one would cause this, however (I've included a plugin list below).

Because FileUtil.write is only ever called from BukkitRunnables I propose the following solution (if this is not caused by another plugin): Don't submit the task to a ForkJoinPool (or at least not the default commonPool), instead just call replaceFile directly.

Testing this, it does not seem to cause a meaningful MSPT increase (< 10 players online).
