Fix #1 playable demos
Merge commit '10bb0130dedf08bec6c2e079d7c5027f6a8f8408'; renamed the files which contained the offending '?' and '&' characters though: bad form, particularly when your dev platform includes non-UNIX storage format (NTFS) or is not a UNIX or otherwise does not allow 'wildcard' characters such as '?' in regular filenames (Windows)
