title: Need currently selected tab ID for jQuery tabs
body: <p>I know I can get the index of the currently selected tab but can I somehow get to the ID (the equivalent of the <code>ui.panel.id</code> if this were triggered by an tab event...but it's not) of the currently selected tab?  I'd prefer not to use the index because ordering of the tabs might change.  I prefer not to use the style markups as those may change in future releases.  Is there a method for this?  If not, can I somehow use the index to access this (maybe even by accessing the panel object first)? Any other ideas?</p>
