Multilanguage Cart Release 1.1.8

Changelog

Type Description
Changed
Manual Integration has been re-enabled because on some webservers it was not possible to use the Automatic Integration (writing permission disabled)
Changed
I've also updated Manual Integration so that instructions reflect the actions performed by the Automatic Integration. Long story short until now I had to manage them as two separate things but now they're based on the same data so it will be a lot easier and faster for me to update all these rules
