clip2icns: switched back to MacOS 8.1 in order to test c2i with older versions. Icon had to be improved since 8.1 uses a different highlighting algorithm. Fixed a bug which would cause a bus error after the icon was inserting (I was disposing of the same GWorld twice). Now the clipboard isn't being previewed, but it's still inserted properly. However it appears that this happens only with MacOS 8.1, and after completely rewriting the code it's still there so I've decided to ignore it for the time being.

nitro: converted more items to the new format, currently I've done 54 out of about 350.
