Originally attribute->type was always 'attribute'
and attribute->signature->type was actual type.
Generator used attribute->type for generating this comment.
Therefore "Type: 'attribute'" was generated (which seems meaningless)

With this patch, attribute->type holds actual type,
so type in comment is now actual type.

Actually, I think we can simply remove the '(Type: ...)' part of this comment.
Currently, changing IDL attributes in an IDL file changes the comment, which
causes rebuild of the generated code. It's ridiculous.

+    // Attribute 'excitingAttr' (Type: 'long' ExtAttr: '')
     {"excitingAttr", TestActiveDOMObjectV8Internal::excitingAttrAttrGetterCallback, 0, 0, 0, 0 /* no data */, static_cast<v8::AccessControl>(v8::DEFAULT), static_cast<v8::PropertyAttribute>(v8::None), 0 /* on instance */},
 };
