Basic Ratchet Skeleton
So far there's a box for the main body and three blades for the grinders.
Adds Ratchet Thruster
I've made a prefab for the Ratchet's thrusters, and imported a premade flame particle for the fire.
The fire particle can be tweaked later since it's a bit big right now.
Basic Ratchet Enemy
This should be enough of a basic version of the Ratchet enemy to start with gameplay programming.
I've made the Ratchet's thrusters a prefab of its own so that we can eventually implement it having multiple thrusters.
