Apparently it's not allowed to set root context properties multiple
times. If one goes to systemsettings, opens effects kcm, closes it
and opens it again it crashes due to setting a context property with
same name again.
This change eliminates the need for the context property by modifying
the property of the QML objects directly.

Currently just opening the Desktop Effects KCM loads QtMultimedia which
in turn loads gstreamer 0.10. If one opens any other KCM in
systemsettings and changes without applying the change, the window
freezes when the warning dialog gets shown, because the warning message
pulls in Phonon with maybe the Gstreamer backend which uses
gstreamer 1.0. This is bad, bad and breaks everything.
By using a Loader the problem scope gets reduced. It still happens but
only if one actually watches a video. Only opening the KCM doesn't
trigger the problem any more.

As we have the split between Effects and Compositor settings nowadays
it's incorrect to have an Compositor related option exposed in the
Effects settings view. Thus the OpenGLErrorView should be removed. As
a nice side-effect that simplifies the main qml file quite a bit by
turning the EffectView from Item into Rectangle.
If it shows that we need the reset GL check in the effects view it would
be better to use a KMessageWidget like in the compositing view.

Introduces partially checked checkboxes for Effects. If an Effect
has an enabled by default function and doesn't have an explicit
value in the config file the checkbox is set to partially. If there
is a value in the config, this will be used.
Clicking on Default will return to the partially checked state.
So far only the built-in effects support the partially checked state
and also the mutual exclusive groups do not support the partial checked
(main reason: RadioButton doesn't support it)

We need kdeclarative for i18n support. This needs to be done before we
load the source. By that we don't need to import Plasma.Core which isn't
used by the views at all.
Also we don't need to link twice against declarative.
Spacing needs to be specified on the ListView instead in the delegate.
This fixes incorrect vertical alignment of the buttons in each row.
In addition a proper background is set on the ScrollView.

Both KCMs had a hard coded default which is obviously bad. Instead we
now calculate a useable implicitWidth and implicitHeight and use this
as the minimum size for the KCM. Which means we need also track changes
to these two root object properties and update the QWidget container
accordingly.

We check whether the effect is scripted and provides a config. If that
is the case our normal approach for getting the config plugin fails and
we use this case to try to load it again through the generic scripted
config plugin.

The model data contains a new role ConfigurableRole. This is used to
decide whether the configure button is available.
The value for the role is set by searching for a KPlugin which has the
effect's service name as X-KDE-ParentComponents. All available configs
are expected to be in kf5/kwin/effects/configs/ and are located through
the KPluginTrader thus binary effect configs need to provide json meta
data.

The new X-KWin-Exclusive-Category property is read from the service
and provided to QML through the ExclusiveRole. If an effect has such
a role the CheckBox is replaced by a RadioButton. The radio buttons of
an exclusive group take care that only one effect of the group can be
enabled. In addition the radio button acts like a check box. If one
clicks the checked radio button it gets unchecked.
At the same time this change removes the hard coded functionality for
the exclusive group of desktop switching effects. It's all handled
dynamically by creating the ExclusiveGroup when needed. For each
category there can be one ExclusiveGroup.

For each effect added to the list the KWin DBus interface is queried
for whether the effect is supported.
By default all effects are set to supported, thus if the DBus service
is not around (e.g. compositing disabled) it is assumed that all effects
are supported. In fact it's not possible to figure it out at all.

Using spacing around the header and no hardcoded color by using
KColorscheme to get the base color and use the same alpha modulation
as KCategoryDrawer.

* use frame in the scroll area
* remove needless anchoring for an Effect
* use one RowLayout for one Effect row
* add a left and right padding using the normal spacing
* Use a ColumnLayout for the center element consisting of
** name
** description
** (info)
** (video)
* Video moved into an own component
* Animations removed

Let's try getting the KCM a little bit less scary by properly
hiding everything the user doesn't have to care about. The prominent
desktop effects KCM only contains the list of all the effects which
can be configured and nothing else. Only exception is the disabled
check after failed GL to make this easier for the user.
All the "advanced" settings are moved into a new KCM called
"Compositing" which is put under the hardware component in
systemsettings. This contains all advanced settings including
* whether compositing is enabled at all
* backend
* animation speeed
* scale filter
* unredirect fullscreen
* color correction

A video button is shown if the model provides an url for a video.
If the button is pressed the video element is added in a similar way
to the aboutInfo and starts the video directly. Once the playback
stopped a play again button is shown.
If one clicks the video button again, the video gets hidden.
Room for improvement:
* add a button to open in external player
* ensure video is centered correctly in the list view
Methods added to the Model to map from row index to the backend
identifier and vice versa. That way the Compositing object can do
all the saving and loading.
* all properties extended to be writable and emit change signals
* contains load from and save to config functionality
* Compositing object in qml view is connected to the values of the
components. So changes are directly mapped from UI to business logic
We have an Apply and OK button in the KCModule, so we don't need one
in the view. A change signal is introduced and passed from the individual
items upwards, so that we can connect to it from the C++ side.
