    MainWindow: escape markup for place description
    
    It is possible to get search results that include characters like '&'.
    We need to escape the markup sent to the search result treeview.
    
    Otherwise we end up with warnings in the console like:
    "(gnome-maps:2368): Gtk-WARNING **: Failed to set text from markup due to
    error parsing markup: Error on line 1: Entity did not end with a
    semicolon; most likely you used an ampersand character without intending
    to start an entity - escape ampersand as &amp;"
