Added the how to play back into the client menu,

Removed some Debugs,
Made the fog not static,

Added fog to the camera

To do:
- Add a starting pen for an 8-player game.
- Add more track sections.
- Add weighting & more criteria for selection of track sections (to produce that escalating difficulty we want).
- Potentially add the possibility for narrower track sections to spawn side by side.
