[1.9] A tool for shuffling log entries

This tool can be used to read a log file and produce an equivalent log file with shuffled entries.
Indeed it still guarantees that the commits are ordered wrt transaction id.
This is a semi-public package (because the kernel test jar is published to allow access to impermanent graph db and a few other things). Could you move this, perhaps to live in the same package as DumpLogicalLog?
