1. Add an emoticon to client/assets/img/emoticons-lg.png
    2. Create a new line for it in style.css with the proper offset
        #kiwi .emoticon-lg.classname { background-position:-##px 0; }
    3. Add a case to kiwi.js for the pattern
        case ':emoteshorthand:':
            pushEmoticonLg(':emoteshorthand:', 'classname');
            break;
    4. Finally, add it to the emoticon pop-up in index.html
            <i class="emoticon-lg classname emoteSelector" value=":emoteshorthand:"></i>
    5. Tweak position in step 2 as needed/desired
