Changed the signature of StringUtils.defaultString(String,String) and (String) to (Object, String) and (Object).

A note needs to be made in the next release that code using defaultString
needs to be recompiled else it will grumble.

 <li>ArrayUtils - opinion seems to be that this belongs with [lang] and not [collections]
