Summary:
Can't add tax value in admin
Detailed Description:
When trying to add a new tax value, and saving the new value, nothing is stored.
Mathieu (AireLibre - Thanks!) made it work:
By adding line 47 of action.defaultadmin.php : $tmp =
cms_utils::get_module('Orders');
Then by replacing in the 3 lines below including "line_item" by
"\Orders\LineItem"
