Setting the frame_direction property of an animation to -1 causes the animation to loop on the first frame. #76

The current code in the animation.update() function looks like this...

else if(this.loop) {
    this.index = 0
}

If you change the code to look like this in the "loop" clause, reversed animations will play correctly

   else if(this.loop) {
      if(this.frame_direction < 0) { 
        this.index = this.frames.length -1; 
      } else { 
        this.index = 0; 
      }
    }

Nice find, can you make a pull-request and maybe a simple test-case for it? :)
