Client holds a SharedPointer to the TabBoxClient and only
provides access to a WeakPointer which is passed to TabBox.
ClientModel is adjusted to hold a list of WeakPointers instead
of the direct pointers.
This fixes the following reproducable crash:
1. Configure both primary and secondary TabBox with different
layouts
2. Use primary TabBox
3. Close a window, best the one which used to be active
4. Use secondary TabBox
-> Crash
The reason is that the ClientModel still contains the pointer
to the deleted TabBoxClient in step 3 and while creating the
layout access to the TabBoxClient is needed to get the Client's
icon.
By using the weak pointer it can be ensured that we don't try
to dereference the deleted pointer and prevent the crash.

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.
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.
