Feature Request: Add CSS Classes

When creating a WordPress theme that uses the Black Studio TinyMCE Widget it is hard to effectively style a widget that users have control over. If multiple widgets are used, and one is supposed to be styled like a contact form, and one is supposed to be styled like an announcement, there is not a way to differentiate these.

The current CSS classes include an enumerated widget class ( widget-3 ) and the general BSTMW class ( widget_black_studio_tinymce )

It would be great if there was an advanced option to add a CSS class to the widget:
