Kleines Weihnachtsgeschenk von der DEC

[TurboMagic]

Hello,

happy new year to all!
The proposed abstract class has been implemented meanwhile and our little joint venture
refactored it out into a separate unit now, to help keeping a good overview.

This also means everybody is invited to add further padding algorithms, especially
if they're standardized

I hope this is as requested now and the only things missing are the documentation and
some unit tests. The former is already being worked on btw.

Cheers
