Status of the spinner ui widget

Status of the spinner ui widget

Hi,

I notice that in some of the early 1.6 release candidates there was a spinner component, which has been dropped.  From looking back through the google code + github repositories, I was able to see where it was dropped, and that it was being moved to a dev branch.  I haven't seen any changes since, and I'm wondering what is happening with it.  

Also, I've made some fixes to the code to get this working with the latest version of JQuery UI. I'm interested in contributing these back, but there didn't seem to be an easy or obvious branch on GitHub to fork and do this against.

Finally, I'm interested in pushing my use of the spinner out into production in the next month, so I'm interested in knowing about any known issues, and why it got pulled out of JQueryUI.

Any help and information would be greatly appreciated.
