Straight forward port. Note: this is currently crashing deep down in
QtQuick. To circumvent the crashes it helps to disable the property
highlightFollowsCurrentItem in the listviews. This solves the problem
that QtQuick crashes on first loading. Unfortunately it still crashes
if one tries to invoke TabBox for the second time.
In effects it's obvious that compositing is enabled, so specifying the
translucent element is no problem.
In tabbox a context property "compositing" is injected which decides
whether "translucent" or "opaque" elements should be used. Here the
translucent elements are only used if the Blur effect is available - for
this a new Effect::Feature Blur is introduced and in addition it is
tested whether the theme provides the translucent element.
Also the masking is adjusted to ensure that only the shadow is not
blurred.
Reason for this change is that Plasma theme seems not always to pick up
whether compositing is used when used from inside KWin. It does not cover
the Desktop Change OSD which uses PlasmaCore.Dialog and there we cannot
(yet) inject that we use compositing.
Overall I'm quite unhappy with this patch and I do hope we can fix it in
the proper place in the lifetime of 4.10 and revert this patch.

due to plasma change, shadow is not included by default, hence kwin
tabbox need to handle shadow by itself, and due to kwin is compositor
and have shadow as effects, it's not a good idea to use X property to
pass shadow from kwin to X and to kwin. This change use the old way to
draw shadow side the tabbox, and partly move the blur region setting to
qml.

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.

The grabbed key events inside TabBox are forwarded to the declarative
view which passes it to the normal keyPressedEvent() method. This
allows the QML files to handle keyboard navigation themselves.
The views support key navigation natively, though this cannot be
used as we need to update the ModelIndex when a new item is selected.
Also there seems to be a problem if the tabbox is shown again, in
that case the focus seems to be somehow lost. Because of that the
navigation is handled in the Item embedding the list.

FIXED-IN: 4.9.0
A new service type is introduced which is used by the KCM to find
all available window switcher layouts. This makes it finally possible
to have 3rd party window switchers.
Also the tabbox finds the packaged QML file through the service
definitions.
Desktop switcher is not yet in packaged version (UI to configure
is missing).
