change showAccessibleTab() to allow a tab id as param as well

According to Marcus' comment here:
http://blog.ginader.de/isok/comment/955/257-jQuery-Accessible-Tabs-How-to-make-tabs-REALLY-accessible.html#c955

Following on from autoAnchor, it would be handy if it were possible to pass the ID value of a tab to .showAccessibleTab() - e.g. tabs.showAccessibleTab("MyTabHeadingID") - instead of only accepting the 0-based index position.

I think either having an integer or a valid jQuery Selector would be the best approach.

fixed in version 1.9
new method showAccessibleTabSelector({valid jQuery selector of the tab to show}) that allows the opening of tabs by jQuery Selector instead of the index in showAccessibleTab()

Thanks for your speedy implementation BUT you don't actually need a new function, nor is it desirable - a jQuery selector can (and often does) return multiple elements, but only one tab can be active at a time, so showAccessibleTabSelector() doesn't make much sense in that context IMHO.

And fortunately, element IDs can't start with a number anyway (part of the HTML spec) so if the parameter passed to showAccessibleTab() is text you should handle it as an ID, and if it's a number you should handle it as an tab array index!
