Turn off animations if they are globally disabled

Respect the graphicseffect level in the system settings. This will disable
all item-animations if the graphicseffect level is "NoEffect".

The smooth scrolling won't be disabled in this case, but the duration has been
made smaller so that it is not recognized as an animation.
