Contraption bugs and balance

- Added a config option to disable the stress/torque mechanic entirely
- Water wheel speed is halved and now configurable
- Water wheels now validate their current speed from time to time
- Fixed windmill bearings counting their sail blocks incorrectly
- Fixed windmill bearings not assembling when placed in a powered block position
- Fixed Contraption controllers not removing their entity reference on the client when disassembled
- Bearings no longer start rotating when no block was found
- Contraptions no longer move unbreakable blocks
- Pistons no longer assemble the whole line of blocks when retracting
- Non-sticky pistons no longer pull blocks back when assembled
- Pulley no longer assembles when the structure by itself is immovable
- Fixed pistons applying reversed motion in some orientations
- Fixed piston contraptions not including the poles into its render bounds
- Fixed Contraptions not culling backfaces when rendered
- Translucent blocks now get moved to the back of the render order in contraptions, fixes hidden block faces between translucent and non-translucent blocks
- Fixed Contraptions being movable through water, fans and other means of applying motion to entities.
- Belt segments can no longer be rotated by a wrench
- Hand cranks are now gated behind brass and sheet production
