commit 2801d67dabe9b57ffe2f044fa93f6302eac63114

    Fix bug where, after double-clicking to switch sheet view, a spurious 
release event was processed.
    
    From 
http://developer.gnome.org/gdk/2.24/gdk-Event-Structures.html#GdkEventButton
    
      Double and triple-clicks result in a sequence of events being received. 
For
      double-clicks the order of events will be:
    
       1.  GDK_BUTTON_PRESS
       2.  GDK_BUTTON_RELEASE
       3.  GDK_BUTTON_PRESS
       4.  GDK_2BUTTON_PRESS
       5.  GDK_BUTTON_RELEASE
    
    So what was happening was this:  When the var-name was double-clicked, the 
view switched
    from VarView to DataView as soon as  event 4 (GDK_2BUTTON_PRESS) occured.  
Then event 5
    (GDK_BUTTON_RELEASE) occured.
    
    Now the PsppSheetView object is written such that, it decides to edit a 
cell, on button
    release event. Hence, whichever cell the pointer happended to be in, when 
the user lifts
    his finger after double clicking, starts to be edited.
    
    This change ignores button release events on the object unless a 
corresponding button press
    event was seen.
