Florian Müllner 2658754295 appDisplay: Merge AppIcon and AppWellIcon
AppIcon is just a tiny wrapper around BaseIcon, which does not add
anything over using BaseIcon directly, so merge its code with
AppWellIcon. As the concept of the "app well" has not been used
since well before 3.0, use AppIcon as name for the merged class.
