removeEditor ----------------------------------------------------------------- Sometimes, the editor should be reinitilized on the fly, e.g. if the body css has been changed (in a CMS the user changed the design template of a page opened in the editor). This method removes the editor from the textarea, adds the changed properties to the base config object and initializes the editor again. -----------------------------------------------------------------
function (cfg) {
        var me = this;

        if (me.noWysiwyg || me.intializationInProgress) { return me; }

        if (!me.tinyMCEConfig) { me.tinyMCEConfig = {}; }
        if (!cfg) { cfg = {}; }


        Ext.apply(me.tinyMCEConfig, cfg);

        if (!me.wysiwygIntialized) { return me; }

        var hidden = true;

        var ed = tinymce.get(me.getInputId());
        if (ed) {
            hidden = ed.isHidden();
            ed.save();
        }

        tinyMCE.execCommand('mceRemoveControl', false, me.getInputId());

        me.wysiwygIntialized = false;

        if (!hidden) { me.initEditor(); }

        return me;
