Module parsing fails if entry contains only elements from module namespace

ModuleParser.java will not parse modules from an element if that element does not contain elements from a module's namespace. This is a problem, because, an entry may still contain attributes from the modules namespace that need to be parsed out.

One solution is to introduce a method hasAttributesFrom(Element root, Namespace ns) which checks an entry for attributes and then use that method in the logic in ModuleParsers.parseModules()
