New features (requested by users):
- WorldGuard support: added flag "season-effects". Setting this to false will disable all season effects in that region. This is done per-chunk for performance reasons, so your region may not perfectly match the unaffected area.
- Added an option to change season names in the config.
- Added a new placeholder for PlaceHolderAPI: %rs_season_<world>% so you can display the season of a world while not in that world.

Bug fixes:
- Fixed an issue with world loading. World data will now be saved In the config instead of the worlds.json file.
- Some biomes were still getting season effects while they shouldn't.
- Packet interception didn't work on some servers, added "protocollib-mode" to the config as a way around. Only use this if you're getting errors from packet interception (contact me first).
