Cyborg Power Usage Overhaul

- Adds new standardised proc for power usage as Cyborg
- Each component now uses different amount of power. Some components use "idle" power (camera), which means constant load. Other components use "active" power, which is single-time burst load.. Example: Actuator.
- Power usage is directly proportional to work done. Moving cyborg uses more power than still cyborg.
- Information in Status tab changed. Now it only shows percentage of remaining charge, as well as cell rating and cell load (W)
