Missile Side Thrusters and new Shader path

Changed the missile model to also include thrusters for rotational purposes and gave them the same exhaust shader.
Each shader is a unique instance and displayed thrusts can be set with set_X_rotational_thrust(), set_Y_rotational_thrust() and set_main_engine_thrust() in the missile root respectively.

Also added a second missile in the space scene just for debugging purposes.
