Allow bean creation with final fields

[tobiasstamann]

It must be possible to create beans with final fields.

Final fields are usually initialized via constructor parameters.
Algorithm must try to map parameters via name.
Otherwise it could be explicitely mapped via an annotation on constructor parameters

Constraints:

• Class must not have a noarg constructor
• Constructor must not have any parameters which can't be mapped to (constant) fields or to super classes

[tobiasstamann]

We could introduce an explicit annotation for constructor parameter mappings, if mapping by name doesn't work.
This could contain also mappings to super class fields (To determine if a parameter initializes a field or not)
