v0.7.1

Two fixes: a network game freeze and the skimmer's flickering jet

Your vehicle no longer stops answering in a network game. In Capture the Banner, a few seconds after you started firing, your vehicle could stop responding to the controls while the game kept running. Working out a weapon's damage briefly makes a throwaway particle, and online every particle is announced to the other players. That announcement wasn't handled on this path, and it stopped the vehicle. It is now sent as everywhere else.

The skimmer's jet stops flickering in Vulkan with Ray Tracing. The round jet at the back of the skimmer was rebuilt with more or fewer pieces depending on how big it looked on screen. While you flew, the camera's distance drifted, and the jet flipped between two shapes from frame to frame. Round parts now keep one shape. The blue glow in the jet's mouth still pulses, as it does in OpenGL and the original game.

OpenGL and the software renderer are unchanged apart from the network fix.
