Sets the model used by combo_box to be model. Will unset a previously set
model (if applicable). If model is NULL, then it will unset the model.
Note that this function does not clear the cell renderers, you have to
call gtk_cell_layout_clear() yourself if you need to set up different
cell renderers for the new model.
