[gtk+/places-sidebar] New signal drag-action-requested

[Federico Mena Quintero <federico src gnome org>]

commit 0a2f9b73131adf422fd3991398385d750e8dde48
Author: Federico Mena Quintero <federico gnome org>
Date:   Mon Dec 3 17:09:57 2012 -0600

    New signal drag-action-requested
    
    We'll use this signal to ask the caller about what drag action to indicate
    when something is being hovered on an item in the places sidebar.
