Added a callback called cleanup to do additional tasks before removing animations

[dhwanils95]

Hello,

I have created a new callback called 'cleanup' which can be called with the hook 'cleaner'. What I wanted to achieve is as follows:
I wanted to write an animation where on the complete callback, I change the position to absolute because it's place is taken up by another element. Now, once the animation was completed the position was set to absolute. But on reset, there was no way for me to set the target's position back to a relative which is what I wanted to do. Right now, I am unable to manipulate the position so I had to find a workaround like this. This is not very specific to my need and I feel many people can use a cleaner function to do something before resetting.

Hey, any update on the status of the pull request? It's been 3 months and I feel this is a very useful feature, a response will be highly appreciated.

Would begin() not do the trick if your problem is setting it back when resetting?
