Changes from 1.1 to 1.2.0

Among them...

• fixed the directory--exclusion bug, completely rewrote routines for including/excluding files
• added pattern matching capabilities
• created MULTIBUF , giving automatic end-of-tape detection
• started modularising the software for faster start up (this also enables you to save disk space by leaving out unnecessary options, important for rescue--disks)
• fixed code for verifying archives
• restructured menus
• KBACKUP now handles filenames containing whitespace properly
• support for mountable block devices
• improved installation program
• changed archive formats (sorry)
