Roughing out the use of adjustments

This fixes wrongly added adjustments.
They are now calculated based on information on the OrderItem and for each OrderItemUnit of said item, we create a new adjustment and add it to the unit.

Introduction to Adjustments

❗❗ Attention: BC break announcement ❗❗
v2.x is not directly compatible/upgradeable with v1 of this plugin, so be aware!

From now on v2 of this plugin uses adjustments to handle customer option prices instead of manipulating the order-item price directly.
This yields more flexibility and domain-correctness of this plugin.

v1.6.1

#41 Save CustomerOption type on OrderItemOption

Compatibility with Sylius 1.4.5

We are now following the Sylius semver with our releases of plugins. Development will continue under the prepatch version number.

Sylius FactoryInterface

Correct factory interface (#36)

• Made OrderItemOptionFactory work like Sylius core factories.

Fixing uninitalized property
