Justify align enabled emoticons, center emoticon image and caption

The word is generic, but it's applied only to  `.emoticons` (CSS output is `.emoticons.enabled { ... }`, HTML is `class="emoticons enabled"`), so I'm using the Cascading part of *C*SS.

I don't mind changing it to `.active-emoticons` if you disagree. Do you mean as an additional class or as a replacement class for `.emoticons`?
