- upgrade scripts added for releases 1.3.x

- my_error function moved from admin/include/functions.php to
  include/functions.inc.php

- because MySQL temporary tables are not always authorized on creation, use
  a temporary table name (with the current microsecond) on a non temporary
  table (in mass_updates function)

- ability to retrieve distant full directories (usefull in upgrade scripts)

- global variables $count_queries and $queries_time moved into global array
  $page

- get_cat_display_name displays category names in correct order : the one
  given by uppercats

- function setup_style simplified

- default value for configuration parameter "show_nb_comments" set to false
  (less queries by default)
