CSS only solution for sidebar and Name box

This submission addresses 3 areas:
1. jQuery UI Tabs spinner option was removed in jQueryUI 1.10 so have provided an alternative solution.
2. Provide CSS only solution to resizing the header accordion - straightforward CSS
3. Provide CSS only solution to resizing the sidebar separator (This uses faux colums as described here: http://css-tricks.com/fluid-width-equal-height-columns/  One True Layout Method). I've made the separator grow to the longest of the sidebar and tabs content. My initial thought was just to make the separator track the sidebar height but when the sidebar is hidden it's height is effectively 0 so an arbitrary height needed to be set. On balance I think the current method provides a better appearance.
