Merged requested to merge github/fork/hwhw/develop into develop

Starting with Firefox 28, DOMTokenListPrototype defines an iterator function called '@@iterator'. That breaks the assumption that all child objects prefixed with '@' are designed attributes.
For now, we'll just skip operations on child objects prefixed with "@@" (i.e. having a second '@' in string position #1 (closed)).
