Colouredtabs

Hi 

I really find the tabs difficult to identify and I'm sure others are also not understanding that their clickable.
Here is a fix to make them coloured (gainsboro); with the active tab being white.

Secondly, Uwe - I think we are on the latest version of Bootstrap which is 2.3.2. I can't see in the recent history if someone had just done this.
