Flicking has to stop at the bounds in the window switcher
layouts. It's not natural on the desktop that they are
flickable in the first place.
Window Strip is unchanged as this layout is intended to be used
on touch and flickable user experiences.

All the default layouts (informative, compact, text, small and big icons)
are rewritten in QML and replace the ListView used before. The old code
is still around for the desktop switching modes which are not yet ported.
Next steps include to update the configuration module to not show now
obsoleted settings as well as providing a better way to choose the layout.
