Simple Carousel - added new features

Hi there,

I've made some changes to your Simple Carousel script.

I've added the option to skip by different numbers of frames than config.visible (named config.jump) and also added the option to disable looping at ends (config.noloop). While looping is disabled the prev/next handle objects will have className `disabled` added to them.

If you have any questions feel free to contact me.

Cheers,
Bart Szczecinski
