Update Cart.php, fix CartItem::fromAttributes call

[PazkaL]

The CartItem::fromAttributes call is missing the $weight parameter, and the CartItemOptions don't work any more because of this.

Sorry for the inactivity, i'll take a look into it but as far it is looking fine. I'll merge asap

@PazkaL While this will fix the issues with the CartIemOptions due to the misused signature, there are some more changes needed in order to make the weight feature work correctly as described in the readme. Could you please enable write access for me so i make these changes to the pull request before merging?

@PazkaL Thanks! I made the necessary changes, the add method should now be in line with the information from the readme file. Please keep in mind that the signature of the 'add' method has now changed
function add($id, $name = null, $qty = null, $price = null, $weight = null, array $options = [])
This change should have already been in 5d117a0, i am sorry for any inconveniences.
