TODO comments

[CoolKangaroo2022]

Hello! I find in your CONTRIBUTING.md that

Don't leave TODOs in the code or FIXMEs if you can help it.

However, I still witness some TODO comments, e.g., unfinished Javadoc for the class in ObjectType.java . I also find TODO comments in the following files:

• game/src/main/java/org/apollo/game/model/skill/LevelUpSkillListener.java
• game/src/main/java/org/apollo/game/model/area/Region.java
• game/src/main/java/org/apollo/game/session/ApolloHandler.java
• game/src/main/java/org/apollo/game/service/GameService.java
• game/src/main/java/org/apollo/game/plugin/PluginManager.java ......

Would you like to remove these TODO comments, or move them to issues, or just leave them alone? If there is anything I can help with?
