So I am using the extended ckeditor by CoolTricks and want to import the emojis plugin. I need to edit:

toolbar: [['Bold', 'Italic', 'Underline', 'Strike', 'RemoveFormat'], ['NumberedList', 'BulletedList', 'Undo', 'Redo', 'Link', 'Unlink', 'Image', 'Blockquote', 'Paste', 'PasteFromWord', 'Maximize']],
removeButtons: 'Subscript,Superscript', // To have Underline back
allowedContent: true,
baseHref: elgg.get_site_url(),
removePlugins: 'liststyle,contextmenu,tabletools,tableselection',
extraPlugins: 'blockimagepaste,image2',
defaultLanguage: 'en',
language: elgg.get_language(),
skin: 'moono-lisa',
contentsCss: elgg.get_simplecache_url('elgg/wysiwyg.css'),
disableNativeSpellChecker: false,
disableNativeTableHandles: false,
removeDialogTabs: 'image:advanced;image:Link;link:advanced;link:target',
customConfig: false, //no additional config.js
stylesSet: false, //no additional styles.js

somehow but I don't know how. Every time I add something it breaks. Help?
