Title: allow :class string attr to specify multiple values, separated by spaces

This matches the behavior of hiccup to allow multiple classes specified in one string. For example:

```clojure
[:div {:class "foo bar baz"}]
```

I am aware that dommy already supports the special :classes keyword, but server-side hiccup does not, so if you want to write some code to be shared between client and server, this helps.
