Multiple changes:

1) Expander Grassy Field level ( A LOT bigger now)
2) Pathfinding system now stops searching once end node is found
3) Coded a script for map camera
4) Added colliders to the entire grassy field env to prevent
uninteresting paths
5) Added and coded an obstacle gate that will open and close every 2
seconds
6) Texture of cat slightly changed
7) Temporarily re-enabled old state controller script for testing
purposes

(We need to fix some nodes (placement) to make sure no null references
occur and path is truly optimal).
