Stronger /me support

As an old roleplayer on IRC and MUSHes/MOOs, I would love for /me to be a little bit fancier than just the italics it gets currently. Prefixing it with the server nickname would be a great start, perhaps akin to the way system welcome/leave messages appear. (Better if it still showed the person's avatar. If not already attached to the current "Cozy Mode" block.) Perhaps too some sort of distinguishing formatting that you can't just replicate in Markdown of a normal message might be cool, too. Again, the more gray coloring of the system welcome/leave messages would be a cool look to replicate. Of course, I realize the risk of making it look too much like system messages and potentially confusing people (or worse), but it would be great to at least see something that feels like its own thing for those times people want to RP with /me messages and not confuse /me messages and italic emphasis, and the system messages are already a great example of how it would look in some old school IRC clients.
