[Laszlo-dev] fix for LPP-4289 "LzDataElementTrait#valueToElement(..)" must be a static-method

[P T Withington]

I think this is annoying but correct.

The proposed (ECMAScript 4 Spec](http://developer.mozilla.org/es4/ 
spec/chapter_9_classes.html) says:

> Unlike in some other object oriented languages (e.g. Java), static  
> properties of the base class are not inherited, but they are in  
> scope in the static and instance methods of the derived class.

I don't know the rationale for that decision.  I think they adopted  
it from [AS3](http://livedocs.adobe.com/flash/9.0/main/wwhelp/wwhimpl/ 
common/html/wwhelp.htm?context=LiveDocs_Parts&file=00000068.html).
