Stable Clonezilla live 2.6.6-15 Released

This release of Clonezilla live (2.6.6-15) includes major enhancements and bug fixes.
ENHANCEMENTS and CHANGES from 2.6.5-21

• The underlying GNU/Linux operating system was upgraded. This release is based on the Debian Sid repository (as of 2020/Apr/28).
• Linux kernel was updated to 5.5.17-1.
• Neglect the line "last-lba:..." for the GPT partition table. This allows something like: 64 GB disk with a 20 GB NTFS partition, disk clone to >= 20 GB disk. This is harmless when same sizes of disk cloning or smaller to larger case. The option -icds is required when larger disk is cloned/restored to smaller one, no need to use -k1 in this case. Thanks to panreyes for this idea. Ref: https://sourceforge.net/p/clonezilla/bugs/342/
• Package pax was included.
• Add scdaemon clonezilla live. Thanks to nurupo for suggesting this.
• Package ufsutils was removed since it's not available in Debian Sid repository.
• Package pxz was removed since it's replaced by pixz in Clonezilla.
• Add batch mode, and instead of countdown, pause it when rc is not 0 for ocs-run-boot-param.
• Add a new program ocs-live-swap-kernel which can be used to swap Linux kernel and modules in clonezilla live.
• Add -z9p in the TUI menu of beginner mode, and now pzstd is replaced by zstdmt when the option -z9p is chosen. Thanks to Lord65 for this suggestion. Ref: https://github.com/facebook/zstd/pull/1192#issuecomment-397599977
