Footer generates two addidional line breaks #784

I see footer generates two senseless linebreaks, it could be removed, and better done via CSS.
```
<div class="footer">
  <br>
  <br>
  <h4 style="color: #999">[ <span style="font-variant: small-caps">base url</span>: http://9.83.253.113:9080/support/knowledgecenter/api/docs
    ]
  </h4>
</div>
```
I just found that code:
line320,swagger-ui.js:
```
buffer += "\n</div>\n<div class='container' id='resources_container'>\n  <ul id='resources'>\n  </ul>\n\n  <div class=\"footer\">\n    <br>\n    <br>\n    <h4 style=\"color: #999\">[ <span style=\"font-variant: small-caps\">base url</span>: ";
```

those BR: ```\n    <br>\n    <br>\n    ``` can be removed,
and margin can be added in ```reset.css```
```
div.footer h4 {
	font-size: 0.8em;
	text-align: right;
	margin-top: 20px;
}
```
20px is just example, but it looks much better & its configurable
