Fixed an issue with the LocalFSArchiveStore, which caused it to set up an incorrect directory, (i.e. /tmpnull instead of /tmp/null/).  Tests should now succeed without root privileges, although you may need to manually remove the root-created target/ folders in each subproject before running the mvn command.

Began implementation on the JPAObjectMetadata class, which is a persistent representation of the ObjectMetadata class.
