Sable Drydock

Changes since 2.38.

• Assembly dock: Loosen moves a welded or hinged part to another place without unwelding it; the weld keeps its points and kind, and Weld makes the same joint again where the part now is.
• Assembly dock: welding two parts that are already joined replaces their weld, so a joint can be changed in place (for example from rigid to a hinge).
• Manager 3D view: the camera also flies like a 3D editor camera (W A S D, Q and E, Shift faster, Alt to look around with the mouse, wheel for speed), stays put when sub-levels are added or resized, and a card in the corner lists the controls.
• Sable Photomancy blueprints now keep manual mass, center of mass and the pairs of sub-levels kept from colliding. Older blueprints load as before.
• Fixed a game crash when joining a world again in the same session with sub-levels kept from colliding or frozen.
• Fixed manual mass and center of mass being lost when a world was loaded again.
• Network protocol changed: the server and every client need 2.49.
