Accordion doesn't open active panel

Regression: Example works in 1.9.x for all browsers, but not 1.10.x

Panel 2 should default to open.

Hi greg.wacker,

Thanks for taking the time to contribute to the jQuery UI project. This was an intentional change made in 1.10 (​http://jqueryui.com/upgrade-guide/1.10/#removed-support-for-non-number-falsey-values-for-active-option). You can use a number to accomplish this: ​http://jsfiddle.net/tj_vantoll/EYCv2/.

Hi greg.wacker,

Thank you for the quick response and example.

That's an unfortunate change to me. I can no longer use a scripting language to dynamically alter classes to determine which panel opens on page load. I now have to break my JavaScript out of a .js file (minified) at some level and instead write dynamic inline JavaScript depending on a user action, which is something I typically try to avoid.

I understand the urge to simplify the UI code base and it's all about where that line is drawn for library performance/size vs features, but I also wanted to point out why some people might find this option pretty useful.

edit: I take last part back to an extent... I guess I can come up with the index based on my active class name in my static .js file just as you had before. More code, but I'm guessing it's not a often used method to warrant adding to the library.
