[Pharo-project] License cleaning: 74 methods left

I did the check again for Pharo #10310 and now we are down at 74 dirty methods. I removed all remaining methods of Richard A. Harmon (RAH) from the list of dirty methods because, as I figured out just now, they originate from the SqueakSource package "ANSI Compatibility", which is released under SqueakL. @Gabriel: this means it would be possible to use the old versions of methods, like #codePoint, you have been working on. The up to date list can be found as usual at: http://code.google.com/p/pharo/wiki/ResultofRelicensing Further help (thanks Gabriel!) is welcome... Cheers, Adrian
