Animations currently not working on some browser-device combinations

[BenjaminBrandmeier]

Image viewer animations are currently not working on (at least) the following combinations:

Desktop + Edge
Desktop + IE 11
iPad Mini + Safari
iPad Mini + Firefox

Maybe this is a general Angular 2 issue. It is working e.g. on:

Desktop + Chrome
Desktop + Firefox
Nexus 5 + Chrome
Nexus 5 + Firefox

Apparently Angular 2 is based on web-animations (https://medium.com/google-developer-experts/angular-2-animate-router-transitions-6de179e00204).

Let's include that polyfill:

Adding the polyfill fixes the issues for all browser combinations listed above. For now IE 11 behaves a little bit juddery. Should create a Plunkr for this and raise an issue.
