A new global method is exported to perform a remote method call
through D-Bus. The call is always performed async invoking a
callback once the call completed passing through the arguments
received from D-Bus.
Possible code looks like the following:
callDBus("org.kde.kwin", "/KWin", "org.kde.KWin", "currentDesktop", function (desktop) {
print("Current Desktop through D-Bus: ", desktop);
});

New properties for the current activity and the available
activities plus related signals in scripts. Signals added to
effects.
BUG: 302060
FIXED-IN: 4.9.0
ScreenEdge is changed to emit a signal whenever a screen edge
got activated without an action or effect taking care of it.
A Script can reserve one to many callbacks for an edge and the
callback get's triggered whenever the signal is emitted. On
deconstruction of the Script the edge is unreserved again.

A CMake variable is used to specify the name of the binary.
By default this is "kwin" but building for PA changes the
name to "kwinactive". The variable adjusts all names, e.g.
kwinnvidiahack becomes kwinactivenvidiahack.
The remaining usage of kwinrc in core and libs is replaced
by a cmakedefine for the configuration name and all data
installations are moved to the defined name. Dynamic loading
for scripts & co is adjusted for loading based on defined name.
This change allows the side-by-side installation of both kwin
for desktop and kwin for Plasma Desktop without the known
issues like conflicts in config files or missing build options
if kwin desktop is used for Plasma Active.
Likewise the KCMs are not adjusted as they are not intended to
be used for kwinactive.

Further debugging functionality for KWin scripts. Added assert
methods validate the to be tested parameter and throw a script
error if the value is not valid.
Following methods are available:
* assert(value)
* assertTrue(boolean)
* assertFalse(boolean)
* assertEquals(expected, actual)
* assertNull(nullValue)
* assertNotNull(notNullValue)
All methods take an additional optional parameter which is used
as the error message if provided.
Methods to validate the number of arguments and types of the
parameters are added and throw syntax or type errors.

A ScriptEngineAgent is added to monitor the execution of a
script. If it ends it stops the script to free resources.
The same is done in case of an exception, just that in this
case the script takes care of unloading itself.

The I/O intensive reading of the complete KWin Script
file into a QByteArray is moved into a thread.
Evaluating and setting up the script engine is still
performed in the main thread.
REVIEW: 104782
Searching for the scripts to load is performed in an own
thread including unloading of already loaded scripts which
no longer should be loaded.
To ensure that two threads are not trying to load/unload
at the same time a mutex is added to protect the list of
loaded scripts.

Workspace emits a signal when the initialization finished and
interested parties can connect to this signal to perform post
init actions. That is everything that does not have to be
performed to have a completely working Window Manager.
As an example loading the scripts is moved into this post init
phase.

This enables the script wrapper objects to automatically create new
dynamic properties for Client objects so that scripts can register custom
properties.
REVIEW: 104697
If workspace is exported as a context property there seem to be
issues with the signals which are not bound to a property of
WorkspaceWrapper.
This problems seems to be fixable by exporting the workspace
property as a global property on the script engine.
As a side-effect this also resolves the issue with the clientList,
so we can drop the hack again.

TabGroup is not (and should not be) a QObject which
makes it rather useless in scripting. In order to use
window tabs in KWin scripts the methods to interact
with tabs from Client should be used.

A global method "registerShortcut" is exported to the scripts which
can be used to register a callback to be called when the global
shortcut is triggered.
The shared code between Scripts and Effects is moved into template
functions defined in a new file scriptingutils.h.

Sometimes Qt is surprising. Apparently QML has problems with a
QList<KWin::Client*> and wants to have a QList<QObject*> which
cannot be used in QtScript.
There ends my dream of having one API for both JavaScript and QML.
So with QtScript it is:
workspace.clientList()
and in QML it is:
workspace.getClientList()
Objects of AnimationData can be instantiated by scripts and expose
all relevant data as properties, so that the ScriptedEffect can
construct the meta value out of it.
This is probably something that could be done a little bit better.
Still need to think about it, so API not yet final.
