Updated tutorials, an easier way to get into the game.

One of the most common feedback I got was that the tutorials where too long or the game too complex to learn, so I changed some things to correct that.

I changed the start of the game to make it faster to get into the action, so you don't have to wait much to start playing.
You start in the exploration screen now, not inside a base.

Also changed the tutorials to make them shorter, making them appear only when needed.

Let me know if these changes fixes that.
