[gtk+/bgo593793-filechooser-recent-folders-master: 5/20] Start in recently-used mode when no folder is set

[Federico Mena Quintero <federico src gnome org>]

commit 252ace66811dbecd91eedcd51e8c7c5bec613e0a
Author: Federico Mena Quintero <federico gnome org>
Date:   Tue Jun 28 17:17:22 2011 -0500

    Start in recently-used mode when no folder is set
    
    In RELOAD_EMPTY mode, when no folder has been selected by the calling app, we now
    start showing the recently-used list.  The rationale is as follows:
    
      - In Open mode, the user is likely to pick a file he has used recently.
    
      - In Save mode, the user is likely to want a destination folder which
        he has used recently.
    
    For the Save case, where we want to present the user with recent folders instead
    of recent files, we will make the recent-list do so in subsequent commits.
