[whatwg] getElementsByClassName() idea

I think this hasn't been suggested before. Perhaps the method should  
accept a DOMTokenString as argument instead of an array. This allows  
things like ele.getElementsByClassName(ele.className) etc. The only  
problem is how to get a DOMTokenString without first getting .className  
 from somewhere. Perhaps it should be a constructor as well. 'x = new  
DOMTokenString("aaa bbb")'

Also,

* The examples use a mix of accepting arrays and strings. This should be  
fixed I assume.

* In "HTML, XHTML, SVG and MathML elements" you can drop XHTML as it's  
clearly defined in the specification what HTML elements means.
