Improved fill progress saving & restoring

+ Added fill progress save to autosave, to avoid lost progress on hard-crashes
+ Prevented fill progress from being deleted except when properly finished or terminated.
+ In case fill progress is saved, but world is not loaded yet when config is loaded, running /wb reload should now resume filling if the world is loaded then.
+ Updated restoreprogress default values to match the current defaults.
