Add config option for auto save

This auto save is inefficient in newer minecraft versions, it pretty much causes lag spikes in newer versions compared to default paper. But since this plugin still has many other good features i think it would be nice for this to be configurable.

That's not enough enabling-disabling bukkit built-in autosave should also set/reset bukkit built-in autosave.

In case of plugin reload you mean? I guess i could save the previous autosave value in a field.

Yes.

Tho most parts of this plugin needs a big rewrite (for example using a single scheduler instead of tons of threads, dynamic load of modules for plugin support, etc). Hope i will find some time to do this in the future.
