[pitivi] Keep the welcome dialog shown when clicking "Missing dependencies..."

[Jean-François Fortin Tam <jfft src gnome org>]

commit b9f62d73083ff6de572fa98e714def138a431ce6
Author: Jean-François Fortin Tam <nekohayo gmail com>
Date:   Sun Nov 3 21:01:19 2013 +0100

    Keep the welcome dialog shown when clicking "Missing dependencies..."
    
    Also prevent GTK3 from messing up the size of the missing dependencies dialog,
    and remove an unused import in timeline/timeline.py
    
    Fixes bug #711357
