Bump oar version to 1.0 from 0.5
If oar contents are being changed such that older versions of opensim can't load them, then the major version must be increased This also locks version parameters to either 1.0 or 0.4, so that arbitrary 'versions' cannot be saved Also closes save stream properly in the event of an error Version 1.0 OARs are currently incompatible with OpenSim 0.7.0.2 and earlier. However, you can still save compatible version 0.4 OARs by specifing --version=0 on the save oar command line e.g. save oar --version=0 oars/test.oar
