[gtk+] GtkListBox: Add a GtkListBoxRow:selectable property

    GtkListBox: Add a GtkListBoxRow:selectable property
    
    Having an explicit property for this will make it easier
    to have a hover style only for rows which are activatable
    or selectable.
    
    Rows are selectable by default, to preserve compatibility.
