[gnome-games/wip/exalm/libhandy4: 6/19] preferences-window: Wrap titlebar into a HdyTitleBar

[Alexander Mikhaylenko <alexm src gnome org>]

commit 394c5554b9a12c624df0c7a048a3e2fd77595a59

    preferences-window: Wrap titlebar into a HdyTitleBar
    
    Also stop setting .selection-mode style class manually, and use
    'selection-mode' property on the HdyTitleBar instead.
    
    This will allow to avoid some glitches in the subsequent commits.
