Implementing the factory in plasma::Animator for new animation objects.

The user should call Animator::create() with the animation type desired
(e.g. FadeAnimation, GrowAnimation, PulseAnimation, etc).

Next: move animation classes to private directory and rename then
so we can use a proper enumeration name.
