Create scene with aesthetic and instructions

[zethon]

Create a new test scene (with the basic requirements for a FPS game (e.g. WASD controls, gravity, etc.) that has basic aesthetic as exterior of this scene.

This should include:

• grey skies
• fog
• wind
• waves in the water
• some basic terrain painting

The basic steps and instructions should be included in the project's Wiki.

For the assignee's information, the project's Wiki can be checked out by adding .wiki to the end of the project name before the .git (i.e. git clone https://<blah>/saintaveline.wiki.git).

I totally forgot to tdo this in a separate scene. I will do so while keeping Game scene untouched.

My largest concern is how we handle terrain in the main scene. This should be addressed very soon. This is so we can have higher detailed sculpting and terrain painting, as currently, the resolution is not scaled well and we can't be precise with terrain sculpting.
