MudGate - player tutorial is live

So, after a few days with my first game online and gaining some real-life game-developer experience.

I have done several small changes based on player feedback, and the major work is a new player tutorial, and making it more context sensitive and guide the players through the start realm at MudGate.

Also I have decided to remove the e-mail requirements for testing the game, so it's easier to test the game.
