new HTML working mode

[rogeliotg]

I really need a HTML pure mode, as init config ideally, where sun editor don't remove html classes or styles.
Right now, I'm using insertHTML with true to populate the editor, and on change I'm ignoring content provided, again with html classes stripped, and using this instead:

            handleChange(editor.current.core.context.element.wysiwyg.outerHTML);

thanks for the great work
