David Steele 148836fe44 Implemented issue #26: Info command.
* Includes updating the manifest to format 4.  It turns out the manifest and .info files were not very good for providing information.  A format update was required anyway so worked through the backlog of changes that would require a format change.

* Multiple database versions are now supported in the archive.  Does't actually work yet but the structure should be good.

* Tests use more constants now that test logs can catch name regressions.
