Returns the node_id representing the preferred translation of the given node.

$mode can be :

• default ; in which case the function will return the node in the current language if available ; if not that in the default language ; if that is not available then the one in the original language.

• original ; in which case the function will return the node in the current language if available ; if not that in the original language.

• an array of language codes ; in which case it will return the first available translation. In that array, the special value 'current' refers to the current language, 'default' refers to the default language, and 'original' to the node's original language. If not match is found the version in the original language is returned.
