[Suggestion] Add option to mention a person/role in messages

[notlet]

When the bot sends a message, it automatically disables all mentions. It would be nice if there was a variable to add a mention that actually mentions people, for example when the server starts up the bot automatically pings a role so people know when it's up.

Also, whenever people get mentioned in the bridge channel, the mention also works in the log channel, which results in a double ping for people with access to both.
