V11 update notes

The water on the shipwreck level now has an "underwater" visual effect and it tracks the color of the water. You need crouch into the water to see it. Or fall of the map. 

Level 0 has been redesigned.

The tutorial level has gotten some improvements.

You can now "preview" some future levels/arenas.

I've started work on implementing a lot more game modes and a progression/challenge system however that's not visible anywhere in game yet. The savefile is now a lot bigger to accomodate all the extra modes and levels that will be coming.
