Subject: [PATCH] Made settings world-specific - look for
 moretrees_settings.txt in your world folder.  If it isn't found, the mod will
 create it with the contents of default_settings.txt and then read those
 default settings and use them. Otherwise, it will read its settings from the
 world folder.
