Major cleanup of item-procs, replaced DB calls by calls to content::item::* in 18of the 24 deprecated procs, just six procs are still required. Commented mostof the affected calls in ::content::item::*
Added the option to rsync instead of tar and scp. This is useful if you have a large number of files in the content repository which you do not want to compress (especially if you have podcasts there)
lower level support for the OO abstraction for stored procedures. reduced per/call overhead relative to Plain OpenACS significantly. The generic call interface is now even faster than calling stored procedures via "db_0or1row".
