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.

cppcheck complained about that piece of code and it was not
really good. A TabBoxClient belongs to exactly one Client which
means the setter should for Client should not be there in the
first place and was only used during construction.

Additional TabBox Mode which allows to switch between all open
windows of the current selected application. By default Alt+tilde
is used which is on qwerty just one key above tab. For non-qwerty
layouts the shortcut is unfortunately not convenient.

If the layout name is specified a custom layout config is
passed to the TabBoxHandler with the configured name.
This can be used by Plasma Active to specify the window strip
(overwrites any settings) and for Netbook shell as a replacement
to opening Present Windows Effect.

DBus method to embedd the TabBox into another window. It follows
the geometry changes and keeps a defined offset to the borders of
the parent window.
Required for Plasma Active's window strip.
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.
Available through DBus. Be aware that this does not make much
sense, as there is no way to end TabBox mode except through the
DBus interface and this does not yet select the selected window.
Therefore TabBox is changed to be controlled without pressing a
modifier key. Tab and Backtab are valid keys now which can be
used to navigate in the list and return, enter and space can be
used to close the box (and select the client).
The TabBox is exported as object /TabBox on the kwin interface
providing start and close methods and signal when the TabBox got
closed.
