Bubble bar dismiss interaction

A single bubble and the bubble stack dismiss functionality is implemented using `BubbleDragController`. It attaches a touch listener to the corresponding views and handles gesture interactions.
* When the view is long clicked the dragging to dismiss interaction starts. It scales up the dragged view and presents the dismiss view in the bottom of the window.
* When the bubble or the bubble stack is dragged close to the dismiss target area, it gets pulled towards it and sticks to it. The `MagnetizedObject` and `MagneticTarget` classes are used for it.
* When the dragged view is released outside of the dismiss area, it moves back to the initial position with animation.
* When the dragged bubble is released inside of the dismiss area, it will dismiss the bubble with animation and remove it from the stack.
* When the dragged bubble bar stack is released inside the dismiss area, all the bubbles will get dismissed and the bubble bar will dissapear.
