getGlobalVar return the var as haxe value (rebased)

[NQNStudios]

I rebased #8 and made the test work on all targets.

On C++ there's an unfortunate behavior where you can't write

var foo:Foo = lua.getGlobalVar("foo");
// foo will be set to null!!

That's because Foo is a class, and the anonymous object returned by toHaxeObj() is not an instance of the Foo class, even though it implements the same interface (although the functions will be null variables because they don't convert).

So to write the test I've done

var foo:{a:Int} = lua.getGlobalVar('foo');

I think supporting Haxe class instance in the current way was a bad decision. I would recommend staying away from that for now until a proper revisit.

[NQNStudios]

If the lua table representing the class instance stored the class name as metadata, the table could be converted back to a haxe object using something like `Type.createEmptyInstance(Type.resolveClass(className))` and then setting the fields i think.
