Subject: [PATCH] shell: Add GtkListBox/Row derived types that do single row
 activations

We often use rows representing different things in the same list
box. In these cases it's often desirable to have rows emitting their
own activation signals instead of having a single handler for the
whole list box that dispatches according to the activated row.
