- replacement of PREFIX_TABLE constant in delete_user function

- deletion of $isadmin variable, replaced by constant IN_ADMIN

- small refactoring

- in include/common.inc.php, deletion of useless part "Obtain and encode
  users IP" and corresponding functions encode_ip and decode_ip

- definition of $conf['default_language'] deleted from
  include/config.inc.php : it is already present in database table config

- function init_userprefs deleted (useless), all its content moved to
  include/user.inc.php

- admin.lang.php and faq.lang.php are loaded only if current user is in
  administrative section
