* Scopes striping to immediate children of the tbody and tr
* For nested tables, sets a background color of @bodyBackground, to override the default transparent bg

* Add simple test to css-tests.html
* Scope .table-bordered to immediate children th/td elements only

* IE8 refused a negative z-index to place the previous :after behind the .arrow, so I had to flip the styles.

* Simplified some of the CSS for the popover carets
