Stop an animation. If you stop an animation only by name then all running animations with that name will stop and emit a complete event. If you stop an animation by id then only that specific animation will stop and emit a complete event. The data argument is as follows:
libgre-plugin-animation.so
The animation name to stop
An optional instance id associated with the name
When the animation stops it will emit a notification event in the form of
gre.animate.complete.[name]
