Integration with jQuery Themeroller (theme aware Timeline)

Hi,

I've successfully integrated the Timeline with jQuery Themeroller. There is no configuration flag. It works as follows:

1) If you don't want to use any jQuery theme, no changes are needed. Simple use the ```timeline.css``` as before.
2) If you want to use any jQuery theme, inlcude ```timeline-theme.css``` on your page (instead of ```timeline.css```). And of course a CSS file for a jquery theme. That's all!

Please see my example ```example26_theming_jquery_themeroller.html``` (link is available in ```index.html```). No worries, I tested it a lot. It looks great with grouping and clustering too.

Thanks in advance.
