Added seasonal encounter pools. They aren't registered in the plugin but if you add them on 03 - Weather Encounters\01 - Encounter methods
(or anywhere else), they should work.
The encounter structure added by this plugin should be one of the following: TypeWeather, TypeTimeWeather, TypeSeason, TypeTimeSeason, TypeWeatherSeason and TypeTimeWeatherSeason. Be sure to follow this structure when registering the seasonal encounters.
The code hasn't been tested so any report of problems will be appreciated.
