Kp c46a0ce27c Remove some remotely-triggerable fatal exceptions 
By design, valptridx will throw an exception on invalid input.  This is
better than silently permitting invalid input to corrupt program state.
Past releases blindly trusted that multiplayer peers would not send
invalid input.  Conversion to the valptridx design eliminated the
undefined behavior when peers send invalid input, but still allowed
multiplayer peers to remotely crash the game by sending invalid inputs.
Add a mechanism to trap invalid inputs and gracefully ignore those
messages.  This may cause game consistency issues, but will not allow
data corruption.
