Ability to change the format of /me

CMDBOOK-2165 - Reported by RustyDagger

My players have recently decided that /me is fun to use That I am fine with i don't wish to take it away from them I do however wish to stop the white text eye rape it creates and make it some thing else that suits my chat colors better.

After looking in the config i was unable to see a way to change the format of it in the messages section.

Ideally it should have a place holder for the name as well as normal color support.

从 /me 命令和 messages 配置部分开始，因为 issue 指出该格式目前尚未在那里公开。完成的标准是提供一个可配置的 /me 格式，并支持名称占位符和常规颜色支持。

由索引模型根据 Issue 内容生成。
