Drone Updates

- Sprites switched on East/West
- Drones can now be picked up by humans
- Drones can now choose to repair a dead drone instead of eating it (free repairs atm, no resource system yet)
- Drone production is Mechfab only now and has correct costs and timing
- Drones can no longer pickup anything that is technically a "gun" including wizard staves
