If there are no windows for Alt+Tab the Show Desktop entry
is shown. This works better with both layouts and effects.
Before this change effects were not activated at all but
a fallback to the layouts was used. Concerning the layouts
some looked rather bad. E.g. Thumbnails did not show a
thumbnail but a legacy text had been shown.
When a window gets added to the empty list, the show desktop
window is removed and consequently when the last window goes
away the show desktop entry is added again.
There is a not considered corner case: if there is no desktop
window, the show desktop functionality is not available and
the behavior is unfortunately undefined. It is a corner case
as we can expect that there is always a desktop window when
using KWin. E.g. there is either Plasma Desktop or Netbook
and on PA there is always at least one window.

This is useful in combination of non-modal TabBox through DBus and
window-strip layout. With DBus the non-modal TabBox can be started
and selecting any item on the strip will end TabBox again.
A new QML item "ThumbnailItem" is registered to the TabBox. The
C++ implementation finds the EffectWindow of the TabBox and adds
itself to the EffectWindow.
While rendering the EffectWindow the information for all registered
ThumbnailItems are extracted and the thumbnail is rendered on top
of the EffectWindow.
This has obvious limitations like you cannot put other QML items
on top of the thumbnail. Nevertheless it works well enough to
be a possible replacement for e.g. BoxSwitch effect.
When compositing is disabled an icon is rendered instead of the
Thumbnail.
One TabBox Layout inspired by BoxSwitch Effect is added. For the
KCM small pre-rendered items are used.

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.
