Martin Gräßlin b265537962 Drop dependency to libplasma from kwineffects library 
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.

Rikkus: please document! (Matthias)
Ok, here's the docs :)
You call delayedShow() instead of show() directly.
If the 'ShowDelay' setting is false, show() is simply called.
Otherwise, we start a timer for the delay given in the settings and only
do a show() when it times out.
This means that you can alt-tab between windows and you don't see the
tab box immediately. Not only does this make alt-tabbing faster, it gives
less 'flicker' to the eyes. You don't need to see the tab box if you're
just quickly switching between 2 or 3 windows. It seems to work quite
nicely.
