title: Twitter bootstrap btn-group-vertical with margin in between the buttons
body: <p>Is there an easy way to add some margin between the twitter bootstrap btn-group-vertical buttons, and to make them all have rounded corners?</p>
  
  <p>My first attempt was to just add some margin between them, using css, but then I saw that, except for the first and last one, none of them had rounded corners, so instead of "playing on", I hope there is a "decent" way to accomplish this...</p>
