Each effect is able to declare itself as currently being active,
that is transforming windows or painting or screen or doing anything
during the current rendered frame.
This change eliminates the hottest path inside KWin identified by
callgrind.

By making Dashboard Effect a fullscreen effect the blurring got
accidentially broken (blur ignores fullscreen effects). Reenabling
by setting the force blur role on the dashboard window(s).
Reapplied commit 629e17d18526ccfae3d3579066e8be927a92437d from KDE/4.6.
CCBUG: 259797
The not initialized boolean value seemed to have evaluated to true
and causing the animation to stop and therefore the darkening not
to apply.
Giving a default value to the EffectWindow pointer doesn't hurt either.
Patch does not apply to 4.6 branch, because of that only in master.

FIXED-IN: 4.7.0
The KWin::TimeLine class was only a small wrapper around QTimeLine
without adding anything to QTimeLine what is not present in QTimeLine.
The initial idea was to make it possible to provide more curve shapes.
This is now obsoleted by Qt shipping more useful curves with QTimeLine.
So let's clean up a little bit and use QTimeLine directly instead of
the small wrapper.
All effects are adjusted to use QTimeLine directly.
EffectsHandlerImpl connects to the Workspace signal clientActivated.
The emitting of the signal is slightly moved from before the activation logic
to after the activation logic. This might change behavior in the scripting
component, but the previous code looked wrong.
Client and Unmanaged use a signal to notify that they are about to be closed.
The EffectsHandlerImpl is connected to those signals and emits the appropriate
windowClosed signal to which the effects are connected.
All previously existing windowAdded methods are renamed to slotWindowAdded.
EffectsHandlerImpl is connected to Workspace's clientAdded signal, which is
emitted a little bit earlier than the previous direct method call. This might
change behavior.
Another signal is added to Workspace to signal that an unmanaged is added.
Since the EffectFrames have been moved into KWin core nothing in the
Effects lib actually used Plasma. The only remaining method is moved
to core as it's not used in the Effects. The Effects itself still
link against Plasma, so nothing changes for them.
The Plasma includes in the kwineffects header seemed to pull in
quite some additional headers, so the includes in some effects have
to be adjusted (most often KConfigGroup). This should speed up the
compilation of the library and the effects.
Prevents that e.g. desktop grid can be activated while dashboard is active.
