request: animation styles

[rockymontana]

Hello.
Just a crazy thought here, but wouldn't it be really nice to be able to set animation freely by passing a configuration based on the ng-animate module?
Maybe that's a whole lot of work?

example:

growl.error("This adds a error message", {ttl: 3000, animation: 'flipX'});

really nice work anyways!

Best
Jonas
