Add Rain and Snow to starter.fps

Hi all getting started guys !

This is how you add rain or snow to the starter.fps


1. copy from example/demo/data the environment folder to
example/starter.fps/data/

2. copy from example/demo/data/sound the environment folder to
example/starter.fps/data/sound/

3. copy from example/demo/server/scripts the environment.cs to
example/starter.fps/server/scripts

4. In example/starter.fps/server/scripts add this line to game.cs

exec("./environment.cs");

5. for the snow make a new snow texture, place the texture in
the example/starter.fps/data/environment folder

6. add this code in enviroment.cs

datablock PrecipitationData(Snow)
{
   soundProfile = "";

   dropTexture = "~/data/environment/snow";
   splashTexture = "~/data/environment/water_splash";
   dropSize = 0.45;
   splashSize = 0.2;
   useTrueBillboards = false;
   splashMS = 250;
};

Try it out !
Hope this helps !
