TPG.Stats.Save

Write the leaderboard to disk, if anything has changed since the last write. Cheap to call: it returns immediately unless something marked the store dirty, which is why the autosave timer, the shutdown hook and the disconnect hook can all point straight at it. On failure it prints a warning and leaves the store dirty, so the next autosave tries again rather than assuming the work is safe. Nothing here deletes a good file before its replacement is in hand.
