AdvancedSeasons 1.10.3

Due to many requests, API jar is now available to download on AdvancedSeasons' github:
https://github.com/AdvancedPlugins/Seasons/blob/main/AdvancedSeasons-API.jar

Changes:

1. Fixed error for servers without placeholderapi
2. Updated `/as info` command when biome is invalid
3. Updated commands with arguments, fixed error when putting in too many arguments

Created a developer API to get/modify seasons, get player's temperature and even boost it. All the methods are explained here: https://seasons.advancedplugins.net/general/for-developers
We'll be adding some hooks from our other plugins to take advantage of this!

Changes:

1. Some updates to season transitions
2. Updated default mobs.yml chance for additional mob spawn

Changes:

1. Added Simplified Chinese locale (Thanks jhqwqmc!)
2. Fully updated default temperature event values and temperatures, to reduce how much gameplay is affected by effects. You can find the changes here: https://github.com/AdvancedPlugins/Seasons/commit/29ba

Changes:

1. Completed reworked temperature events. Now they use our Abilities engine (https://wiki.advancedplugins.net/abilities/introduction) to allow full customization of temperature events. You must reset the temperatures.yml file or upload the new one: https://github.com/AdvancedPlugins/Seasons/blob/main/temperature.yml#L38
2. Updated sleeping mechanics (plugin now handles all sleeping)

Changes:

1. Updated %advancedseasons_season% placeholder to show current season
2. Seasonal shop now refreshes once season changes
3. Updates to some default season colors

Changes:

1. Added config.yml setting `temperatureActionbar` to toggle status actionbar
2. Added config.yml setting `temperatureEventsActionbar` to toggle temperature events
3. Added PlaceholderAPI placeholders https://seasons.advancedplugins.net/general/placeholderapi-placeholders
4. PlaceholderAPI is now supported in the seasons' actionbar

Changes:

1. Updated internal API version for pupur servers

Changes:

1. Sleeping in a bed will now skip the night and count calendar days.
2. Added setting in temperature.yml to toggle temperature events - temperatureEventsEnabled
3. Updated commands to not require world name.
4. /season addworld command no longer overrides whole config
5. Only water source blocks will freeze in winter.
