Add English pronounciation of "Krzysztof" to en_dict

This commit adds the usual English pronunciation of my name to the English dictionary.

We could, alternatively, add the native pronunciation, `kS'I2StOf` (or the closest approximation to it I could get out of the English synthesizer), but I'm not sure what the policy on that sort of thing is within the project.
