Animations

child of #3649

We need another round of animation fixes. We never found a solution to the bad performing animations. With the upgraded Angular we now have access to more ngAnimate classes and we might be able to do a full CSS-animated solution now instead of relaying on javascript animations and a 3rd-part library.

PR: #3897

The PR reenables the infinite editing animations.

How to test:

• Open an infinite editing workflow (Ex. add a property to a doctype)
• Make sure the infinite editing panels slide in and out

@madsrasmussen so do animations now perform well? I can confirm it all works, just don't know if this now performs better based on what code has changed since there's not really optimizations in the code.

I've merged it in but just want to know how it performs better or if we are just going to accept the performance (for me it's seemed ok)
