/**
* More advanced language substitution
* Function to mimic sprintf() with the possibility of using phpBB's language system to substitute nullar/singular/plural forms.
* Params are the language key and the parameters to be substituted.
* This function/functionality is inspired by SHS` and Ashe.
*
* Example call: <samp>$user->lang('NUM_POSTS_IN_QUEUE', 1);</samp>
*
* If the first parameter is an array, the elements are used as keys and subkeys to get the language entry:
* Example: <samp>$user->lang(array('datetime', 'AGO'), 1)</samp> uses $user->lang['datetime']['AGO'] as language entry.
