Adding Contrite TfT

[drvinceknight]

This strategy plays like TfT in an environment with no noise. If there is noise it has the following added capability:

If it is defected against because of noise (ie as a mistake) then it responds by cooperating twice.

This requires a bit more information as we don't currently have a way for a player to know if an opponent's play was returned because of noise or not. @marcharper pointed out the TrackHistoryTransformer which allows a player to track it's own intended play. Perhaps something like that could be used.

Based on the explanation here I think ContriteTFT only has to look at its own history. If it has to examine the opponent's history then it doesn't obey the standard rules...

Ah! Awesome. That makes this much simpler :)
