Multiple class selectors

[aalmiray]

Rather than

styleClass: ['my-list', 'special-list']

would be groovy to have

styleClass: 'my-list special-list'

In reference to http://dev.w3.org/html5/spec-preview/global-attributes.html#classes

...the class attribute is split on spaces. (Duplicates are ignored.)
The space characters, for the purposes of this specification, are U+0020 SPACE, "tab" (U+0009), "LF" (U+000A), "FF" (U+000C), and "CR" (U+000D).
