Subject: [PATCH] bfojcapell: Added function insertBeforeRecursive (see
 www.silverstripe.com/google-summer-of-code-forum/show/3005). This function is
 only called in Translatable.php at this moment, so if finally insertBefore
 gets a recursive behaviour then the call can be renamed and
 insertBeforeRecursive deleted. (merged from branches/gsoc)
