Comment (by malu):

 Here is a first patch against im.pidgin.pidgin.custom_smiley implementing
 custom emoticons using XEP 0231.
 It works quite nice for me.
 I haven't tried it much with MUCs. There also seems to be an issue when
 sending messages to offline buddies, where sometimes the message is
 silently dropped (but not always) when containing an emoticon. This may be
 because of a size limitation.
