Modify site publishing scripts to include gremlint

I think `bin/generate-home.sh` just needs to run the `npm` command to generate the static site and copy it to `target/site/gremlint` and then hopefully, `bin/publish-home.sh` will automatically note the new `gremlint` directory and upload it svn to publish. If it doesn't, there's probably some minor changes to `bin/publish-home.sh` to accomplish that step.
