new voice-messages, a bit more level to play, cheats

I said that if someone beat it, I'd add more levels. 2 people tell me they've beat it (one in about 37 minutes on first try. Much shorter is possible if you skip a lot). I only have had time to add a little level content for now - I have more planned. The hardest part is testing.

Liara and ScottyBoiV contributed amazing voice messages so I needed to add them to the update. I never expected this level of contributions, nor level of emotion I've experienced testing the game while listening to user-contributed messages.

There is also a cheat menu (C) now, used for skipping to checkpoints.
