(050a72bf3) Server resets remote character inputs if no inputs have been received in the past 0.5 seconds. Previously the server would assume the inputs hadn't changed from the last known ones, which works well when there are brief networking hiccups that cause the server to run out of inputs for a few frames, but if it takes longer, we don't want to keep the character firing a welding tool or whatever else they were doing until the kill disconnect timer kicks in.
