Title: Add ability to automatically prefix properties

Here's my go at auto-prefixing as per our conversation in #64:

```clj
user=> (css
{:vendors ["webkit"]
:auto-prefix #{:border-radius}}
[:.foo {:border-radius (px 3)}])
".foo{border-radius:3px;-webkit-border-radius:3px;}"
```

Let me know what you think!
