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.
