Show some player actions in chat

[GrimPixel]

To prevent cheating, I think the actions need to be announced in public when objects are added, deleted, shuffled, etc.

This could be a room setting (similar to physics setting). Like: "Announce actions in chat"

I could see more messages being added for expensive operations, like setting the room state via a save file - but simple operations like adding and removing pieces seem very verbose, and could very easily flood the chat.

I've got a couple of ideas in mind:

• As well as [INFO], [ERROR], and [WARN], maybe a new [VERBOSE] type could be added that is disabled by default?
• If there were print_verbose or print calls added throughout the code, maybe these could be viewed in some sort of in-game console? That way, the messages would also go to the logs and help with debugging.
