Owen W. Taylor 5111edb80b Use a St.Bin rather than a St.BoxLayout for calendar popup
Using a horizontal St.BoxLayout for calendar container forces
width-for-height layout on the St.Table child. Since St.Table
is naturally width-for-height, this can trigger bugs and is,
at best, a bit ineffecient. Use a St.Bin instead since we don't
need any BoxLayout features.
