[RF] AquaMai configuration refactor (#82)

更新了配置文件格式，原有的配置文件将被自动无缝迁移，详情请见新的配置文件中的注释（例外：`SlideJudgeTweak` 不再默认启用）
旧配置文件将被重命名备份，如果更新到此版本遇到 Bug 请联系我们

Updated configuration file schema. The old config file will be migrated automatically and seamlessly. See the comments in the new configuration file for details. (Except for `SlideJudgeTweak` is no longer enabled by default)
Your old configuration file will be renamed as a backup. If you encounter any bug with this version, please contact us.
