Sticky footers without any wrappers

This approach is much cleaner, smaller and simpler to understand and it works with IE8+, Chrome, Safari, Firefox, Opera!

Here are the example in action without any `#wrap` divs:
[sticky-footer-navbar](https://dl.dropboxusercontent.com/u/15234/bootstrap/docs/examples/sticky-footer-navbar/index.html)
[sticky-footer](https://dl.dropboxusercontent.com/u/15234/bootstrap/docs/examples/sticky-footer/index.html)

That's the new CSS for sticky footers without the `#wrap` looks like this:

    html {
      position: relative;
      min-height: 100%;
    }
    body {
      /* Margin bottom by footer height */
      margin-bottom: 60px;
    }
    #footer {
      position: absolute;
      bottom: 0;
      width: 100%;
      /* Set the fixed height of the footer here */
      height: 60px;
      background-color: #f5f5f5;
    }
