Chatbox can spoof people to click message to run danger commands

[zyxkad]

Describe

Chatbox can send any formatted messages, which means if people send /op ckupen in run_command action, or /kill @e. An op or other player may click it under an illusive information, then everything goes well.

We should add a blacklist to say which command action cannot be send or suggested.
