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.

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.

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.

Whenever the KWin configuration is changed, scripting has to unload
scripts no longer loaded and load the scripts which have been added.
For this new methods are introduced to check whether the script is
loaded.

New global method readConfig is exported to QtScript and declarative scripts.
Config is read from a config group stored in kwinrc called "Script-<pluginname>".
For this the ctors of the AbstractScript and derived classes are changed to also
take the pluginname.
For this the Script class is slightly refactored to have a common
base for JavaScript and QML based scripts.
Why QML bindings? This allows to use QML for example for the
desktop change OSD or for fullscreen effects like Present Windows.
Scripts are found by the KServiceTypeTrader and can now be
enabled/disabled. Loading of config is currently disabled. Will
be made available again after scripted effects are merged.
For this a new MetaObject "KWin" is exported to have the
enum ClientAreaOption available in scripts. Unfortunately this
requires duplicating the enum from kwinglobals.h.
The idea is to extend the wrapper to have it wrapping even more
functions provided by Workspace. Of course it would be possible to
just add the properties to Workspace itself and export this. But I
think complete Workspace is just too powerful to fully expose to
scripts. So a small wrapper around the parts which are usefull for
scripts might make more sense.
This breaks now also the API for Workspace and again it is already
more powerful with less code than before.
For this properties are defined in ClientGroup and several methods
are changed to be slots (to be invokable from scripts). On Client
the clientGroup is exported as a property.
The existing wrapper around ClientGroup is dropped as it is no
longer needed. Interestingly it was wrong anyway as it allowed to
construct a new ClientGroup, which has to be done internally.
At the same time the meta declarations get cleaned up a little bit.
Whatever it was, we cannot need a "Lazy Logic (TM)" which is not
documented. And even if it were useful, KWin is not the right place
to develop language extensions to ECMAScript.
Each KWin Script is also exported as a D-Bus object and can be
stopped (destroyed) and started through D-Bus. Output and errors
are emitted as D-Bus signals. That allows external applications
(e.g. Plasma desktop scripting console) to load a script and print
out the output.
The general interface is exported as /Scripting and allows to load
a new script by file. The script is not directly executed but only
loaded. To execute it the run method on the script object has to be
invoked.
Every disorder causes every duration, which ensures the one that stays.
reality is relative. natural is disorder.
