change --old-guids switch on the save oar command line to --version=<x>

if x is 0, then an old version 0.3 archive is saved.  If it is anything else or missing, then a version 1.0 archive is saved
version 1.0 archives cannot be loaded on OpenSim 0.7.0.2 and earlier
also add various informational notices about what version we've saving/loading
