Title: Fix conflict with bootstrap 2.x icon style. 

In bootstrap 2.0.3, the icon style is:

```
[class^="icon-"],
[class*=" icon-"] {
display: inline-block;
width: 14px;
height: 14px;
*margin-right: .3em;
line-height: 14px;
vertical-align: text-top;
background-image: url("img/glyphicons-halflings.png");
background-position: 14px 14px;
background-repeat: no-repeat;
}
```

And I found the `vertical-align` and `background-image` will break the display of the icon.
