Fix up tablet detection

Android < 4.4 doesn’t report the user agent the same, so we bail out if
we can know we are a tablet, otherwise, we check the device’s size /
pixel ratio. If it’s > 900, tablet. (This is, I realize, entirely
arbitrary)
Add destroy method
Android 4.x fixes

Added outline suppression to DIVs and TEXTAREAs; adjusted flex-boxes to
work. (Note: you should always specify at least the center button group
if you intend on a right button group properly displaying)
