[gnome-games/wip/exalm/views: 6/19] ui: Add DisplayView

[Alexander Mikhaylenko <alexm src gnome org>]

commit 8ba05d0acd373ccec576adf58e159b7b48468003
Author: Alexander Mikhaylenko <exalm7659 gmail com>
Date:   Thu Oct 4 17:59:26 2018 +0500

    ui: Add DisplayView
    
    This will be used in the subsequent commits to move game display logic out
    of ApplicationWindow.
    
    Make 'box' and 'header_bar' public temporarily, until their references in
    ApplicationWindow are removed.
