Fix utf8 issues in calls to md5_hex.
This prevented comments containing some utf-8, including euro sign, from being submitted. Since md5_hex is a C implementation, the string has to be converted from perl's internal encoding to utf-8 when it is called. Some utf-8 happened to work before, apparently by accident. Note that this will change the checksums returned. unique_comment_location is only used when posting comments, so the checksum does not need to be stable there. I only changed page_to_id for completeness; it is passed a comment page name, and they can currently never contain utf-8. In teximg, the bug could perhaps be triggered if the tex source contained utf-8. If that happens, the checksum will change, and some extra work might be performed on upgrade to rebuild the image.master
