Server DOCUMENT_ROOT used instead of FCPATH

In footer_js.php and head.php
Server DOCUMENT_ROOT used instead of FCPATH
Causes issues when installing this in a sub-folder, and not using "web" for the root.

this are not necesary, solved by defining right way the index files:

$config['base_url'] = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on') ? 'https' : 'http';
$config['base_url'] .= '://' . $_SERVER['HTTP_HOST'];
$config['base_url'] .= str_replace(basename($_SERVER['SCRIPT_NAME']), '', $_SERVER['SCRIPT_NAME']);
