fixed reports configuration

This PR addresses two related issues:
- The new combined reports bundle `edu.gemini.spdb.reports.collection` comprises five bundles in ocs2, and we never hooked up the old activators or tuned the manifest correctly, so none of it was really working. I fixed the manifests and added code in the primary activator `edu.gemini.spdb.cron.osgi.Activator` to delegate start and stop events to the other four old activators. At some point we should merge these cleanly, but for now I'm leaving them as-is in case we decide to split them back apart for some reason.
- The reports bundle was only included in production `spdb` app configs, so I moved it up to the `common` config. To test batch report FTPing and so on, adjust the `cron` batch settings for your personal configuration.

Note that the reports and batch entry points are on port **8442** at `/reports` and `/batch` ... I was looking on 8443 and was very confused for a while.
