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.

Tested it in the racetrack scene it gets a list of all the objects at runtime so when the functions are called will trigger them one at a time.
Also got the characters moving correctly with the conveyor belts and the shooting cannon.

Only tested in tutorial scene and hard coded the "Character" name, set up to get names or characters animals based on the connected clients list, but has yet to be tested

Changed the prefab for the cannon to instantiate the shooting object each time, and a bool to specify if it will push characters left or right, made it easier for figuring it out and calling the right coroutine
added coroutines to character script
