/groupmirror command #114
Description
In addition to the /groupsource command, since FA links don't embed properly (especially NSFW submissions), it would be nice if the bot could detect FA links being posted in a group and automatically perform the mirror command so a proper preview comes up when someone shares an FA link.
To do this, I imagine a /groupmirror command would do the trick and have basically the same toggling functionality as /groupsource.
