Title: accordion's data-parent can't contain dots

jQuery is throwing when it encounters "[data-parent=anything.with.a.dot]".

Failing fiddle (look in the console to see the error): http://jsfiddle.net/jdiamond/tqDZd/

The fix is to quote the value for data-parent when finding the elements to hide.

Pull request contains both a unit test and the fix.
