- removed the "graphic switch" because it causes portal errors
- Then I was able to re-add collision to some models (and player clips to make a good navigation)
- few optimisation fixes

- Changes in the environment lighting (increased the ambient and changed a bit the brightness of the sun light)
- Better optimisation
- Changed the name to "pool_day" instead of "fy_pool_day"
- Added a kv file to change CT and T skins
