Fix handling of dCpy with resource fork

Browse Source 
DiskCopy disk images on HFS volumes, such as the ByteWorks Opus ][
CD-ROM, have resource forks.  The double-click handler was screening
out forked files, so double-clicking on one of these disk images
was popping open the file viewer instead of creating a new instance
of CiderPress.
