Shark Game mode:
-Changed the model of the shark to egg shark to match the theme of the game
-Increase the round that the water raises from round 6 to round 7 in the map "scene_a_lighting"
-Added health bar to the sharks
-Added notification sound effect for when a player joins your game room in the lobby game room stage. This will help let you know when a player has joined your match. Hopefully this will help players wait a bit in the lobby game room for other players to join
-Removed aim training game mode
-Removed trees from "scene_a_lighting" because it causes frame drops and lags
