Sets a classStyleScheme to be used by the buffer and the view.
Note that a classStyleScheme affects not only the syntax highlighting,
but also other classView features such as highlighting the current line,
matching brackets, the line numbers, etc.
Instead of setting a null scheme, it is better to disable syntax
highlighting with gtksource.buffer.Buffer.setHighlightSyntax, and setting the
classStyleScheme with the "classic" or "tango" ID, because those two
style schemes follow more closely the GTK theme (for example for the
background color).
