- improvement: long localized messages are in HTML files instead of $lang

array. This is the case of admin/help and about pages.

- deletion: of unused functions (ts_to_mysqldt, is_image, TN_exists,
  check_date_format, date_convert, get_category_directories,
  get_used_metadata_list, array_remove, pwg_write_debug,
  get_group_restrictions, get_all_group_restrictions, is_group_allowed,
  style_select, deprecated_getAttribute).

- new: many new contextual help pages to replace descriptions previously
  included in pages.

- modification: reorganisation of language files. Deletion of unused
  language keys, alphabetical sort. No faq.lang.php anymore (replaced by
  help.html). Only done for en_UK.iso-8859-1.
