clean testing code + comments

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.

Corrected the connectedclients list
Still need to set up the environment turn to trigger the animations

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

Modified the pit prefab (sorry Claire), the surrounding blocks clashed with neighbouring pits/walls/water/etc.
Starting the game will now take you to the 4-player alpha racetrack rather than Colour Collide.
Camera now scrolls along the racetrack level at a rate of 1 block per turn. Currently nothing happens to people who fall behind it, except that you can't see them.
Pets will no longer paint blocks in their colour. (I had to modify the ColorCollide.cs script for this, as I could not figure out how to turn a script into a .asset object as was done for ColorCollide.asset.)
