Fix the spawn stuff

Turned on the video for the client main menu,
fixed error with cannon missing link for text

Added the how to play back into the client menu,
Fixed the block spawning issue (ran about 10 rounds with no errors),
Added another counter for the cannon so it shows both sides,
Removed some Debugs,
Made the fog not static,
Players can sucessfully disconnect from the game - their character is also removed and the server doesnt wait for their input

Added a overlay/shadow to the lobby names to make theme easier to read,
Added a coloured background and animal sprite to the client background so players remember who they are

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

Got blocks spawning based on the players locations
Removed duplicate logic blocks(Correct colours are back!)

Added fog to the camera

Lobby fix to display 8 names
Icons in client scene
Small Menu changes - remove tutorial scene

changed the start prefab so i dont have to play like 20 rounds of the game until i can die, will change back after more testing

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.

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
