Fix crystal and boulder prefab and loss of life

checked max players (it was already 8?!?),
fixed timing on the boulder and crystals - less inbetween wait time = less time between rounds

Added fog to the camera

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.

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
