QSCarrier items. This includes making the tap targets 48dp high.
* Added contentDescription to alarm icon in QS Header info
* Changed icons to ones without inset so views are properly aligned
* Made text in QS header marquee
* Reduces vertical margin between tiles in landscape to fit 2 rows (when
not in VPN).
