Control swing cat animation by mouse events with rx

[akryvomaz]

still need to be done:

• synchronization between cat body and mouse events
• animation for press (touch) + hold

Not sure what to do with the presentation, because I can't really demo how we control the cat with the mouse and that is actually the main difference of controlled animations.

Lets finish this, I will demo it at my next presentation! Currently I think people won't understand the difference.
