[gtk+/gtk-2.90] Make get_selected_file() return a ref'ed file

[Christian Dywan <cdywan src gnome org>]

commit d7571ab99dbd55fdcef3b04a0dbcec211308ab31
Author: Federico Mena Quintero <federico novell com>

    Make get_selected_file() return a ref'ed file
    
    The old semantics was to return a GFile* owned by the file system model; the new
    semantics is to hand out new references whenever possible.
