Feature #4

[Sytten]

• Behavior now have to choice to override only the function they need (because they are now virtual instead of abstract)
• Now always use behaviors to react to environment (Creates the landing behavior)
• Creates the wheel behavior (The hero is placed correctly when colliding with the wheel and rotate with it)
• Update the wheel prefab (with a new collider and behavior)
• Fixes a bad offset in the hero prefab
