[Pas2js] Pas2js 0.9.31

[warleyalex]

a) When I compile a project using document.getElementsByClassName I always
get the 
--> Error: identifier not found "getElementsByClassName"
There's a minor type at the web unit:
    function getElementsyClassName(aNames : string) : TJSHTMLCollection;


b) To be able to work with pas2js, the Lazarus IDE needs to be told where
the source files are. I usually compile the 4 packages. The
fpcunit_pas2js.lpk package does not compile anymore.

d) In a experimental project I've got a mysterious "Fatal: Compilation
aborted", there is no errors displayed in the console. It could be many
things: Delphi code causing exceptions; DOM manipulations causing errors;
not implemented feature, etc. Any thoughts? In a future can be a feasible
solution:
 
console.log(AError.AMessage+#13+AError.AFile+#13+{%LINE%}+':{%COL%}+#13+AError.AStack);
