Title: Field tracking for PojoPropertyDescriptors

I implemented the traceability of Fields for `PojoPropertyDescriptor`s if possible. Thus a `PojoPropertyDescriptor` now has a reference to its representing `Field`.
If the `PojoPropertyDescriptor` cannot be traced to a `Field` `getField()` will return null.
