Bug: Three bugs with the hinge

[nikitabr0]

1. If the hinge has been activated since launch, the parts connected to it will move to wrong coordinates in the build menu, when reverting to build.
2. When I activate the hinge and update one of the parts, that is connected to it, the other parts move to coordinates, that don't make sense.
3. When recreating the second bug, I stumbled upon another: sometimes the parts, connected to hinge start to spin and there's no way to stop it.

To Reproduce
Steps to reproduce the first bug:

1. Attach some parts to the hinge
2. Spawn the rocket
3. Activate the hinge
4. Revert to build

Steps to reproduce the second bug:

1. Attach any part to the hinge
2. Attach an updatable part to the parts attached to the hinge (for example: heatshield)
3. Spawn the rocket
4. Activate the hinge
5. Update the updatable part (for example: detach the heatshield)

The third bug just happens occasionally.

(GitHub doesn't allow files larger than 10MB, so I had it cut it into two parts)
