[gtk+/places-sidebar: 31/53] Add functions to say whether multiple tabs/windows are supported

[Federico Mena Quintero <federico src gnome org>]

commit 7be881982f02f7811db5f59593fdb80bdc50e453
Author: Federico Mena Quintero <federico gnome org>
Date:   Tue Oct 4 09:22:11 2011 -0500

    Add functions to say whether multiple tabs/windows are supported
    
    The file chooser will leave these off by default; file managers
    like Nautilus will turn them on.
    
    These control whether the places sidebar shows 'open in new tab' and similar
    items in its context menu.
