getElementsByClassName() rewritten

Andy has rewritten getElementsByClassName, resulting in much cleaner code and a method which can be called on any DOM element, not just the document object.

Doesn't work in IE whatsoever, much to my annoyance!

The reason for not working in IE is given in MSDN Library, local msdn-url:
ms-help://MS.MSDNQTR.2003FEB.1033/script56/html/js 56jserrfunctiondoesnothavevalidprototypeobject.htm
Which states that

(...) external object types (are) not valid JScript objects. An external object can be an object from the host object model (for example, Internet Explorer's document or window object), or an external COM object.

So a workaround in IE... nothing better than to define the getElementsByClassName() as a global function and throw in the actual Element-object as a parameter...
