WIP -- "website" submodule is blocking progress

These changes are about making build with packages work without requiring a
separate workspace directory above the package directory, so for example moving
the bootstrap1-registry into Bootstrap.1/registry.  The "website" module isn't
in the catalog but is a dev dependency. I could just remove it as a dev
dependency to make progress. Or I could work on improving the state of the
integrated website and doc generation....
