The standard SpinBox uses far too much real estate.
The new SpinBox have a smaller footprint, and more visual effect.
Changing the TemplateSpinBox, automatically changes all spinboxes
in the system, converted to the new layout.
The styling would be better in a style/theme class, but
subsurfaceTheme is in main.qml and not in a C++ class, so for now
use primitive styling.
