Subject: [PATCH] Added $forcelang optional parameter. This is useful if we
 want to get help.php to display the help content in a language irrespective
 of the site language settings. This is needed for /admin/helpdoc.php script.
 This view requires previews for:

1) en_utf8
2) the current language the site is set to

Without the change to /help.php, 1) is not possible.
