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.

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.

Effects that need GLSL require that OpenGL 2 is active.
It does not matter whether the GPU would support it if
OpenGL 2 is not used.
Cherry-picked from db42152

Creating an EffectFrame requires I/O which takes on my system
during testing between 10 and 40 msec. Also it needs a little
bit of memory.
This changes moves out the creation of EffectFrames at Effect
load till the Effect actually needs the EffectFrame. E.g. if a
user does not filter in PresentWindows there is no need to ever
create it.
BoxSwitch effect is ignored as it should be dropped for 4.9.

Cube effect loads 0 to 2 textures which has been
performed during configuration. This change delays
loading the textures till cube is activated for the
first time and the loading from file is moved into
a thread.
This means that for a very short time the texture
is not yet visible, but this is not a problem as
the cube animates from fully opaque starting state.
So during the loading the texture would not be
visible anyway.

Client::manage calls setupCompositing on the not
yet fully managed client before it wants to create
the window decoration. This means the decoration is
created twice and maybe even if not needed (noBorder
not yet set).
If the Client is not yet managed setupCompositing
will not update the decoration - it will be handled
by manage later on.
Furthermore if compositing is not active, setup
compositing does not have to perform any action.

By moving the query for effects into an own thread the
startup does not have to wait till all effects are loaded.
The thread moves the loading of the effects after the
Window Manager and Compositor has been fully initialized.
This is possible as EffectsHandler is fully functional even
without any effects.
The compositor ensures that at least one frame is rendered
before the started thread returns which makes the complete
startup more responsive.
