Clean up the Dashboard Example

Created by: mrmv

The dashboard example is a nice starter template but is has some issues / needs some cleanup.

1. It uses the outdated .container-fluid classes, this should be the bs3.container (i assume with a width:100% override) 2. The sidebar should allow scrolling if the content is too long, the css for .sidebar could be someting like

@media (min-width: 768px) {
  .sidebar {
    position: fixed;
    top: 51px; /* use a top offset */
    left: 0;
    bottom: 0;
    z-index: 1000;
    display: block;
    padding: 20px 20px 20px; /* 50px less on padding-top now we have a top offset*/
    overflow: auto; /* make it scrollable */
    background-color: #f5f5f5;
    border-right: 1px solid #eee;
  }
}
