Add more helper functions to simplify module code

[takaro-ci-bot]

Description

Add more helper functions to simplify module code, such as 'PM' for private messages. This will make it easier for users to write and understand modules.

Requirements/use-cases

• Users should be able to use short, intuitive helper functions like 'PM' instead of longer, more complex code.
• Helper functions should cover common operations in modules, such as sending messages, creating variables, etc.
• The new helper functions should be well-documented and easy to understand.

Examples

• Instead of gameServerController.sendMessage, users can use PM for private messages.
• Create a helper function for creating variables with simpler arguments.
