I added a new set of emoji/smilies. The full list and shortcodes for them can always be found here. The main set can be found by clicking the smilie face on the post editor -- this is available via quick reply as well. However, in the full posting mode there's a tab level for "extras" that have some other smilies hidden in there and if I add more at another time they'll be there as well. These are from Twitter's open-source project of emoji, if anyone has others that they think would be cool to add or a better set please let me know.
