Use gtk_tree_selection_select_range().

You already have the start path, so, how to get the end path?  Use
gtk_tree_model_iter_n_children() and gtk_tree_model_iter_nth_child()
recursively to always move to the last child in the branch.  If your
tree is only two-level (as it seems to be) you do not even need to
recurse.
