add animationHolder for css animations

These elements (actor, modal windows) are moved around via css transforms (translation). The animations also use css transforms (scale). The translation is more dominant because its directly applied to the element. Applying both transforms to the same element would require to apply both of them via javascript. I want to keep the animation in the CSS files. To give the animation transforms its own 'namespace', a second DOM element with the class 'animationHolder' was created around the elements content.
move modals via css transforms (faster)
add gesture support detection
hide zoom slider only when gesture support is detected
