Creates a new #GtkSourceFileLoader object. The contents is read from the
#GtkSourceFile's location. If not already done, call
gtksource.file.File.setLocation before calling this constructor. The previous
location is anyway not needed, because as soon as the file loading begins,
the buffer is emptied.
