End of the year cleaning

Wanted to get rid of all the codes I have, so I'm just going to dump them here.
Some of the in-game codes probably can't be activated anymore, but you can always try.
Sorry to make steam keys a bit difficult, but it at least hopefully prevents one person of getting everything.
Don't ask how to activate in-game items, I haven't tested.

Oh, and be a sport and post if you take something so others don't have to try in vain.
