Adds an attribute mapping to the list in @cell_layout.
The @column is the column of the model to get a value from, and the
@attribute is the property on @cell to be set from that value. So for
example if column 2 of the model contains strings, you could have the
“text” attribute of a GtkCellRendererText get its values from column 2.
In this context "attribute" and "property" are used interchangeably.
