jquery-waypoints doesn't exist

It doesn't exist anymore and now when I `bower install angulartics` I get this:

```
~/Desktop
🍔  $ bower install angulartics

Additional error details:
No versions found in git://github.com/imakewebthings/jquery-waypoints.git
```

This resolves this issue, though the demo may need some updates to the path for the js file or something...
