New features:
- Added a world restorer. Use this if you want all the seasonal changes done to your world by this plugin undone. Usage: /rs restoreworld
- Added an option to the config to disable snow placement by all snowmen (requested feature)
- You can now do /rs reload from the console

Bug fixes:
- Fixed errors when "setting spawn-chance-mobs" to lower than 2.
- Fixed manual config changes getting undone when the plugin shuts off.
- Made sure the plugin loads after multiverse so all worlds are loaded.
