Async connect and train follow — Steam Revolution: The Age of Rail Steam update #47416

NetworkGame will retry connecting to the server if it becomes disconnected.Game now connect asynchronously, reducing startup/network stalls.If the server version/protocol doesn't match, the game stops retrying that session, resulting in clearer behavior and fewer unnecessary connection attempts.SimulationFixed a bug where if trains merged such that the second train was closer than the follow distance, it would not slow down and would crash into the train in front of it. There was actually a second related bug where it would come to a complete stop instead of crashing into the train in front of it. This was exposed by fixing the first bug. Now train merges are detected correctly and trains will gently slow down until they reach their ideal follow distance. Fixed bug where trains following another could match the speed of the leader even if they should not be able to due to track curvature...
