Many style/formatting edits. Bug fixes. Reverted some previous changes temporarily while reviewing new code. Merged Baker's "virtual device" in a simpler form. ODS2 will assign a sensible drive name when mounting /image (== /virtual). If a specific drive name is desired, mount /image drivename=filespec. Files can be quoted, or use set qualifier_style unix if slashes are a problem. Note that mount on the command line allows tab completion. Moved "statistics" command into show. Coded support for import/binary (fixed records, 512 bytes). Converted fgets to fgetline Added show devices for Unix (limited by standard APIs) Got rid of separate ODS2-Image build.
