New
- Adds a new /season info command
- Adds a new /season leaderboard command
- Adds new placeholders to support the leaderboard

Fixes
- Settings from `world` `world_nether` and `world_end` were not properly copying to the seasonal worlds. For example, having "Hard" set on the default world, wouldn't copy to the new "season_world" and would result in an "Easy" world isntead.
- Same issue with "IsHardcore"
- Same issue with "PvP"

Changes
- Change the way that some code was being managed internally. This should have no impact to performance.
- Change the localization.yml to a new version.
- Change the config.yml to a new version.

Upcoming
- Planning to update the scoreboard with more "Dynamic" data.
- Planning to make the scoreboard more "Vertical" and less "Fat"
- Planning to add a custom config for the scoreboard independent of the info config.
- PAPI? Maybe?
- Planning to add a separate scoreboard with player activity stats.
