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.
The first signal used between EffectsHandler and Effects.
The signal is actually emitted by the EffectsHandlerImpl and only
the interested effects connect to this signal.
EffectsHandlerImpl itself is also notified by a signal from Workspace,
allowing to remove one of the many if (effects) checks.
its own directory, cleaned up the effect config macros and renamed
"MakeTransparent" to "Translucency" so that it matches its visible name.
