Making it work in ST 2.2.1

[tralves]

Hi!

Thanks for the awesome menu! I am using ST 2.2.1 and had to make a couple of changes, both in controller/MainContainer.js

1. line 55:

var velocity  = Math.abs(e.deltaX / (e.timeStamp - e.startTime)),

Apparently e.deltaTime no longer exists.

1. line 70:

this.moveContainer(offset.x,100);

If you don't add a duration to the animation, the animation doesn't occur and the animation listeners (ln. 161) don't fire.

I forked/branched this project with my changes here.

If you want me to pull request, say so.

Again, thanks!
