1.5

• added BS-DOS 308 a its native container *.MBD,
• unreadable sectors no longer participate in import but are skipped (and automatically marked as bad in FAT),
• added a simple mechanism to detect a previous crash of the application,
• fixed import of incorrect tape file checksum (e.g., if the checksum is 39 and it's incorrect, then even though it must be imported as 39),
• added button to re-calculate checksums for selected tape files,
• fixed export/import of tape files whose official and real lengths differ (motivation: Piškworks), and added a new column to File Manager, informing on real length of the data,
• fixed import of headerless tape files (a collision of proxy-names),
• a tape file *.TAP can now be opened by dropping it on a write-protected disk (eventually, nothing is imported, just a new tab is created for the opened tape),
• fixed refreshing of File Manager,
• added button to navigate to the previous directory in File Manager.
