DCing algorithm

[Silverthorn]

I don't have any r-lf2-files on my comp right now, so I cannot test the decrypter with them. However, I just tried the "stupid" unreadable-making-method, where you just replace the first few bits. It works fine, and I think this is the encryption method of r-lf2. (Of course it works, I know how me and Silva coded :P)

But just to prevent any questions, CE-LF2 dat-files are encrypted in a different way, and with this code you cannot decrypt them either.
