Support Symfony 2.2 PropertyAccess with BC for 2.1 (closes #218)

Browse source 
By abstracting the property access, we can easily support Symfony 2.1's Form component and 2.2's PropertyAccess component.

The PropertyAccessor service will be injected into transformers if it is available. Tests were modified to do the same, and expect the appropriate exception depending on which implementation is available.
