Fix for doctrine mappings issues in ShippingBundle.
Add backend form error messages

Currently global form errors (extra fields, csrf, etc) are not displayed in backend.
This commit adds one to discuss if this is the desired approach. (will do all if OK).
Fix Shipping Method Calculator form prototype handling

Currently, switching the calculator field in the ShippingMethodType embeds calculator config prototypes under __name__ key, which causes the form to not validate. This commit makes the following changes:
 * use the proper field name (configuration)
 * skip embedding forms for calculators that don't support configuration (currently results in empty text field being embedded)
Fix translation & make it more consistent

Carts should be singular, and wording is now more consistent throughout site.

Fix Inventory Unit Mapping

The orphan-removal flag is on the wrong side of the association and is discarded by doctrine.
This leads to Order::removeInventoryUnit() failing to cascade properly, and makes the cart update fail when reducing the quantity of any item in the cart. Marketing would love to keep this bug, I'm sure ;)
