Fix SceneManagment of enemies

[jChicote]

Description

A problem that is coming up is that there needs to be a way of managing the enemies within a scene. The worryis that we will ramp in feature complexity and developing enemies will be unmanageable

Main Areas of concern:

• Management of enemy toggling during scene transition or loading of enemies.
• Managing the behaviour tree depending on which scene the player is in

Additions:

• Create a seperate pipeline for handling deactivation of the scene and is triggered by the same additive scene trigger
• Group all service objects and components into the same master object.
