Sets a #GtkSourceStyleScheme to be used by the buffer and the view.
Note that a #GtkSourceStyleScheme affects not only the syntax highlighting,
but also other #GtkSourceView 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
#GtkSourceStyleScheme with the "classic" or "tango" ID, because those two
style schemes follow more closely the GTK+ theme (for example for the
background color).
