tagging 6.x-3.1

Completly reworked module to be able to maintain the D6 and D7 code at the same type using OOP in that case.
- API did not change
- i removed Alchemy and extractor suggestions due the lack of support and bugfixing of the initial authors

Anything but that, it just should work :)

Thank you for Comm-Press and Lukow - both donated the full budget to make this port happen!
