Put the "Copy Message" function back.

The "copy message" option is no longer available, and for apparently no reason other than being user-hostile. Put it back.

It was extremely easy to use rather than having to highlight and ctrl + c messages, especially long ones, and preserved both the formatting and the use of emotes rather than just copying the emote name in the :emote: format.

Why take this out? It helps nothing and only makes the application worse. Put it back.
