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.

The branch contains the first step in reworking the kwineffects
library. This includes:
* replacing virtuals by signals and slots
* dropping some unused methods
* remove KWin::TimeLine
More to come.
Conflicts:
kwin/workspace.cpp
First a signal is emitted when the user starts a move/resize operation.
During the move/resize operation each geometry change emits an update signal.
Last but not least a finish signal is emitted.
This eliminates the specific method for geometry updates in drawbound resize
mode.
1. The I18N_ARGUMENT_MISSING that appears when moving or resizing one
window. The problem happens because when declaring the variables
myResizeString, myCoordString[0] and myCoordString_[1] i18nc tries to
replace %1, %2, %3, and %4, but those arguments are not passed here.
Using #define we avoid the argument passsage.
2. Replace QString::arg() with direct formating, which is better for
performance.
I know we should avoid #define but in this case I think it is the best
option. If anyone has a better alternative feel free to change this
commit.
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.
