Creole10.g typos and date changes

Hey Jim,

I found this typo while reviewing some Javadoc. I edited the `Creole10.g` file to update the generated Java classes. I ran `ant build-creole-parser` to regenerate the classes based on the grammar file. There were some additional changes when I regenerated, but they seemed to be pretty minor and I assume these were done, probably, because these classes have not been built in a while. Let me know if you see any red flags. Thanks!
