Draft NX2 worldmax unlocks

Because this information is scatter across the whole internet,
incomplete and often also incorrect, I got these directly out
of the game. I hope "transcribing" them didn't introduce any
mistakes. I cross checked some of them with codes that I found
on various sites.

Numeric pad codes are to be entered on a num pad. That format should
be converted to images also before using them.
