Patch - Snapshot on Squeak/Windows

Hi all, Ive already sent this to the map owner, but from browsing the mailing list archives today for other isses I am having, it looks like the mailing list could do with it too. Im running smallwiki on windows. I couldn't get the image to snapshot until I put this fix in. It makes sure that the change file gets closed before it is copied. I don't know if this is just Windows weirdness or not, but it would be sensible to close the change file in other OS's as well.
