Luboš Luňák 2a87593638 Add a global configuration option for animation speed. See description
of Effect::animationTime() for how-to-use.
TODO: Effects need to reload config after doing the change in the kcm.
NOTE: Default TimeLine constructor now creates invalid object, it is
necessary to explicitly call setDuration() in order to ensure all
animations respect this setting.
