sg3_utils-1.37 and ddpt-0.93 betas; xcopy work

Since several people are working on xcopy; I have collected various fixes, improved documentation and debug to sg_xcopy (in sg3_utils) and ddpt into new betas dated today. They can be found in the News section at the top of:

There are a lot of other fixes to sg3_utils (see its ChangeLog) so I intend to release version 1.37 soon.
