public void add_class (string class_name)
Adds a style class to this, so posterior calls to @get or any of the gtk_render_*() functions will make use of this new class for styling.
In the CSS file format, a Entry defining a “search” class, would be matched by:
<!-- language="CSS" -->
entry.search { ... }
While any widget defining a “search” class would be matched by:
<!-- language="CSS" -->
.search { ... }
